1.5µA IQ, Step-Up DC-DC Converters in Thin SOT23-5
General Description
The MAX1722/MAX1723/MAX1724 compact, high-efficiency, step-up DC-DC converters are available in tiny, 5pin thin SOT23 packages. They feature an extremely low 1.5µA quiescent supply current to ensure the highest possible light-load efficiency. Optimized for operation from one to two alkaline or nickel-metal-hydride (NiMH) cells, or a single Li+ cell, these devices are ideal for applications where extremely low quiescent current and ultra-small size are critical. Built-in synchronous rectification significantly improves efficiency and reduces size and cost by eliminating the need for an external Schottky diode. All three devices feature a 0.5Ω N-channel power switch. The MAX1722/ MAX1724 also feature proprietary noise-reduction circuitry, which suppresses electromagnetic interference (EMI) caused by the inductor in many step-up applications. The family offers different combinations of fixed or adjustable outputs, shutdown, and EMI reduction (see Selector Guide). o o o o o o o o o o o

Each part contains one driver and one receiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps.The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them to transmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consume only 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-load receiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, while the MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________ApplicationsLow-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level TranslatorsTransceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features♦For Fault-Tolerant ApplicationsMAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 TransceiverMAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers♦For Space-Constrained ApplicationsMAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 TransceiversMAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 PackageMAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe ReceiversMAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-855/RS-422 Transmitters ♦For Multiple Transceiver ApplicationsMAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters ♦For Fail-Safe ApplicationsMAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceivers♦For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kV ESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 TransceiversMAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________Selection Table19-0122; Rev 8; 10/03Ordering Information appears at end of data sheet.M A X 481/M A X 483/M A X 485/M A X 487–M A X 491/M A X 1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSSupply Voltage (V CC ).............................................................12V Control Input Voltage (RE , DE)...................-0.5V to (V CC + 0.5V)Driver Input Voltage (DI).............................-0.5V to (V CC + 0.5V)Driver Output Voltage (A, B)...................................-8V to +12.5V Receiver Input Voltage (A, B).................................-8V to +12.5V Receiver Output Voltage (RO).....................-0.5V to (V CC +0.5V)Continuous Power Dissipation (T A = +70°C)8-Pin Plastic DIP (derate 9.09mW/°C above +70°C)....727mW 14-Pin Plastic DIP (derate 10.00mW/°C above +70°C)..800mW 8-Pin SO (derate 5.88mW/°C above +70°C).................471mW14-Pin SO (derate 8.33mW/°C above +70°C)...............667mW 8-Pin µMAX (derate 4.1mW/°C above +70°C)..............830mW 8-Pin CERDIP (derate 8.00mW/°C above +70°C).........640mW 14-Pin CERDIP (derate 9.09mW/°C above +70°C).......727mW Operating Temperature RangesMAX4_ _C_ _/MAX1487C_ A...............................0°C to +70°C MAX4__E_ _/MAX1487E_ A.............................-40°C to +85°C MAX4__MJ_/MAX1487MJA...........................-55°C to +125°C Storage Temperature Range.............................-65°C to +160°C Lead Temperature (soldering, 10sec).............................+300°CDC ELECTRICAL CHARACTERISTICS(V CC = 5V ±5%, T A = T MIN to T MAX , unless otherwise noted.)

The MAX481, MAX485, MAX490,MAX491, and MAX1487 can transmit and receive at data rates up to 2.5Mbps, while the MAX483, MAX487,MAX488, and MAX489 are specified for data rates up to 250kbps. The MAX488–MAX491 are full-duplex trans-ceivers while the MAX481, MAX483, MAX485, MAX487,and MAX1487 are half-duplex. In addition, Driver Enable (DE) and Receiver Enable (RE) pins are included on the MAX481, MAX483, MAX485, MAX487, MAX489,MAX491, and MAX1487. When disabled, the driver and receiver outputs are high impedance.MAX487/MAX1487:128 Transceivers on the BusThe 48k Ω, 1/4-unit-load receiver input impedance of the MAX487 and MAX1487 allows up to 128 transceivers on a bus, compared to the 1-unit load (12k Ωinput impedance) of standard RS-485 drivers (32 trans-ceivers maximum). Any combination of MAX487/MAX1487 and other RS-485 transceivers with a total of 32 unit loads or less can be put on the bus. The MAX481/MAX483/MAX485 and MAX488–MAX491 have standard 12k ΩReceiver Input impedance.Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 8_______________________________________________________________________________________Figure 2.

Figure 12 shows the dri-ver output waveform and its Fourier analysis of a 150kHz signal transmitted by a MAX481, MAX485,MAX490, MAX491, or MAX1487. High-frequency har-monics with large amplitudes are evident. Figure 13shows the same information displayed for a MAX483,MAX487, MAX488, or MAX489 transmitting under the same conditions. Figure 13’s high-frequency harmonics have much lower amplitudes, and the potential for EMI is significantly reduced.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers_______________________________________________________________________________________9_________________________________________________________________Test CircuitsFigure 4.

Receiver Enable and Disable Times (except MAX488and MAX490)Table 1. TransmittingTable 2. ReceivingLow-Power Shutdown Mode (MAX481/MAX483/MAX487)A low-power shutdown mode is initiated by bringing both RE high and DE low. The devices will not shut down unless both the driver and receiver are disabled.In shutdown, the devices typically draw only 0.1µA of supply current.RE and DE may be driven simultaneously; the parts are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the parts are guaranteed to enter shutdown.For the MAX481, MAX483, and MAX487, the t ZH and t ZL enable times assume the part was not in the low-power shutdown state (the MAX485/MAX488–MAX491and MAX1487 can not be shut down). The t ZH(SHDN)and t ZL(SHDN)enable times assume the parts were shut down (see Electrical Characteristics ).It takes the drivers and receivers longer to become enabled from the low-power shutdown state (t ZH(SHDN ), t ZL(SHDN)) than from the operating mode (t ZH , t ZL ). (The parts are in operating mode if the –R —E –,DE inputs equal a logical 0,1 or 1,1 or 0, 0.)Driver Output ProtectionExcessive output current and power dissipation caused by faults or by bus contention are prevented by two mechanisms. A foldback current limit on the output stage provides immediate protection against short cir-cuits over the whole common-mode voltage range (see Typical Operating Characteristics ). In addition, a ther-mal shutdown circuit forces the driver outputs into a high-impedance state if the die temperature rises excessively.Propagation DelayMany digital encoding schemes depend on the differ-ence between the driver and receiver propagation delay times. Typical propagation delays are shown in Figures 15–18 using Figure 14’s test circuit.The difference in receiver delay times, | t PLH - t PHL |, is typically under 13ns for the MAX481, MAX485,MAX490, MAX491, and MAX1487 and is typically less than 100ns for the MAX483 and MAX487–MAX489.The driver skew times are typically 5ns (10ns max) for the MAX481, MAX485, MAX490, MAX491, and MAX1487, and are typically 100ns (800ns max) for the MAX483 and MAX487–MAX489.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________1110dB/div0Hz5MHz500kHz/div10dB/div0Hz5MHz500kHz/divFigure 12.

For line lengths greater than 4000 feet, see Figure 23.Figures 19 and 20 show the system differential voltage for the parts driving 4000 feet of 26AWG twisted-pair wire at 110kHz into 120Ωloads.Typical ApplicationsThe MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 transceivers are designed for bidirectional data communications on multipoint bus transmission lines.Figures 21 and 22 show typical network applications circuits. These parts can also be used as line repeaters, with cable lengths longer than 4000 feet, as shown in Figure 23.To minimize reflections, the line should be terminated at both ends in its characteristic impedance, and stub lengths off the main line should be kept as short as possi-ble. The slew-rate-limited MAX483 and MAX487–MAX489are more tolerant of imperfect termination.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________13DIV Y -V ZRO5V 0V1V0V -1V5V 0V2µs/divFigure 19.

Determine the COM port by look-ing in Control Panel→System→Hardware→Device Manager and expand Ports (COM & LPT). The port is COM5 in the example shown in Figure 2.Figure 1. DS9481R USB-to-1-Wire/iButton Adapter and CableiButton Adapter i Button DevicesYou have now completed the installation of the DS9481R adapter. Obtain the adapter software and directions for installation for your 1-Wire/iButton peripheral device by contacting the Analog Devices online Technical Support Portal.RJ11 PinoutTable 1 and Figure 3 show the RJ11 pinout mounted on the DS9481R PCB at J1. The RJ11 pin 1 can supply 3.3V and can be used for auxiliary board power. The GND is the ground of the 3.3V supply. The signal OW (DATA) stands for the 1-Wire data bus. The ground return for OW (DATA) is the signal OWGND. The PULSE signal is to be used as the VCC power supply for OTP 1-Wire peripheral parts. The PULSE signal is typically 3.3V, but also canprovide the needed programming pulse for OTP parts.The GP signal is reserved for future general-purposeusage and is functionally not used by the DS9481R.Mini-USB PinoutThe 5-position Mini-USB type AB connector is mounted atCN1 of the DS9481R PCB, as shown in Table 2.Hardware/Firmware CapabilitiesThe DS9481R uses both the Prolific PL-2303GC andthe Analog Devices MAXQ610. The PL-2303GC is fullycompliant with the USB 2.0 specification for the Windows11 and Windows 10 OS and provides a bridge for theUSB-to-UART connection. The MAXQ610 is loaded withfirmware that emulates the functionality of the DS2480Bserial-to-1-Wire line driver at a lower 3.3V operationvoltage. The MAXQ610 functions as a UART-to-1-Wirebridge and can serve custom application needs with firm-ware programmability.Table 1. 1-Wire RJ11 PinoutTable 2.

艾麦克3CX1500A7 8877高功率三极管说明书

The Eimac 3CX1500A7/8877 is a rugged ceramic and metal power triode designed for use as a cathode driven Class AB2 or Class B amplifier in audio or rf applications including the VHF band, or as a cathode driven anode modulated Class C rf amplifier. As a linear amplifier, high power gain may be obtained with excellent intermodu-lation distortion characteristics.Low grid interception and high amplification fac-tor combine to make the 3CX1500A7/8877 drive power requirements exceptionally low for a tube of this power capacity.Overall Dimensions:Height ...........................4.02 in: 102.16 mm Diameter .........................3.83 in; 85.85 mm Net Weight ..............................25 oz; 708.8 gm Operating Position ......................................Any Maximum Operating Temperature:Ceramic/Metal Seals & Anode Core.. ....250° C Cooling .............................................Forced Air Base .............................................Special, 7-pin Recommended Air System Socket:Grounded Grid ...............................SK-2210 Grounded Cathode ........................SK-2200Recommended Air Chimney (teflon) .........SK-2216CHARACTERISTICS 1Cathode: Oxide Coated, UnipotentialHeater Voltage .........................5.0 ± 0.25 V Heater Current at 5.0 Volts ...............10.5 A Minimum Warm-up Time ..................3 Min.Transconductance (Average):I b = 1.0 Adc ............................55,000 µmhos Amplification Factor (Average).................. 200Direct Interelectrode Capacitances (grounded grid)2 Cin ....................................................38.5 pF Cout ..................................................10.0 pF Cpk .....................................................0.1 pF Ck-htr .................................................9.7 pF Direct Interelectrode Capacitances (grounded cathode)2 Cin ....................................................38.5 pF Cout ...................................................0.1 pF Cgp ..................................................10.0 pF Frequency of Maximum Ratings ........ 250 MHz1Characteristics and operating values are based upon performance tests.

Adjustment of the rf grid voltage to obtain the specified anode current at the specified bias and anode voltages is assumed. If this procedure is followed, there will be little variation in output power when the tube is changed, even though there may be some variation in grid current. The grid current which results when the desired anode current is ob-tained is incidental and varies from tube to tube. These current variations cause no difficulty so long as the circuit main-tains the correct voltage in the presence of the variations in current. If grid bias is obtained principally by means of a grid resistor, the resistor must be adjustable to obtain the required bias voltage when the correct rf grid voltage is applied.RADIO FREQUENCY POWER AMPLIFIERClass C, Cathode Driven Plate ModulatedRADIO FREQUENCY POWER AMPLIFIER Class B Telegraphy or FM(Continuous Operating Conditions)ABSOLUTE MAXIMUM RATINGS: DC ANODE VOLTAGE................. 4000 V DC ANODE CURRENT ................... 1.0 A ANODE DISSIPATION .................1500 W GRID DISSIPATION ....................... 20 W CATHODE-TO-HEATER VOLTAGE ...250 VdcTYPICAL OPERATION - 88 - 108 MHz)Measured Values Class B, Cathode DrivenANODE VOLTAGE ........................ 20002500 3000 4000Vdc CATHODE VOLTAGE 1,2 .................... +9 +12 +15 +20Vdc ANODE CURRENT..............................1.0 1.0 1.0 1.0Adc GRID CURRENT 2..

This may be contacted by multiple clips or flexible finger stock. Connec-tions to the heater and cathode are made via the 7-pin base. The Eimac SK-2210 socket is recommended for all rf amplifier applications.STORAGE – If a tube is to be stored as a spare it should be kept in its original shipping carton, with the original packing material, to minimize the possibility of handling damage. Be-fore storage a new tube should be operated in the equipment for 100 to 200 hours to establish that it has not been damaged and operates properly. If the tube is still in storage 6 months later it should be operated in the equipment for 100 to 200 hours to make sure there has been no degradation. If opera-tion is satisfactory the tube can again be stored with great as-surance of being a known-good spare.COOLING - The maximum temperature limit for external tube surfaces and the anode core is 250°C. Tube life is prolonged if these areas are maintained at lower temperatures. For full 1500 watts anode dissipation 35.0 cfm of air is required at a back pressure of 0.41” H 2O hold tube temperature below 225°C with 50°C ambient temperature at sea level. At frequen-cies higher than 30 MHz, or at high altitudes, the air quantity must be increased. The data shown is based on airflow in the base-to-anode direction.average design value for each rating below the absolute value of that rating by a safety factor so that the absolute values will never be exceeded under any usual conditions of supply-voltage variation, load variation, or manufactur-ing variation in the equipment itself. It does not necessarily follow that combinations of absolute maximum ratings can be attained simultaneously.HEATER OPERATION – The heater power supply should be isolated from ground (ie.; no center tap on the sec-ondary of a transformer if used). The rated heater voltage for the 3CX1500A7/8877 of 5.0 volts, as measured at the socket, should be maintained at this value to obtain op-timum performance and maximum tube life. In no case should the voltage be allowed to deviate from 5.0 volts by more than plus or minus five percent (5%). This tube is designed for normal commercial service, where one heater on/off cycle is anticipated per day. Contact Eimac Application Engineering if more daily on/off cycles are ex-pected.CATHODE WARM-UP/COOL-DOWN TIME - It is recom-mended that heater voltage be applied for a minimum of three minutes before anode voltage and drive voltage are applied, to allow for proper conditioning of the cathode surface. It is also recommended that after all voltages are removed from the tube that air cooling be allowed to run for several minutes to allow for proper cooldown.INPUT CIRCUIT - When the 3CX1500A7/8877 is operated as a cathode driven rf amplifier, the use of a resonant cir-cuit in the cathode is recommended. F or best results with a single ended amplifier, it is suggested that the cathode tank circuit operate with a “Q” of 5 or more.ZERO-BIAS OPERATION - Operation at zero-bias is not recommended with anode potentials over 3000 volts, since anode dissipation may be exceeded. Higher anode voltage may be used with proper protective bias.FAULT PROTECTION - All power tubes operate at volt-ages which can cause severe damage in the event of an internal arc, especially in those cases where large amounts of stored energy or follow-on current are involved. Some means of protection is advised in all cases, and it is rec-ommended that a series resistor be used in the anode circuit (20 to 50 ohms) to limit peak current and provide a means of dissipating the energy in the event of a tube or circuit arc. F or an oxide-cathode tube such as the 3CX1500A7/8877, a maximum of 4 joules total energy should be permitted to be dumped into an internal arc. Amounts in excess of this may permanently damage the cathode or the grid structure. Additional information is found Eimac’s Application Bulletin #17 titled “FAULT PRO-TECTION,” available on request.NOTES:1. Tube mounted in SK-2200 Socket with SK-2216 Chimney.2. An allowance of 25 watts has been made for grid dissipation and 50 watts for filament power.ELECTRICALABSOLUTE MAXIMUM RATINGS - Values shown for each type of service are based on the “absolute system” and are not to be exceeded under any service conditions. These rat-ings are limiting values outside which serviceability of the tube may be impaired. In order not to exceed absolute ratings the equipment designer has the responsibility of determining an3CX1500A7/8877SEALEVEL10,000FEETAnode Dissipation (Watts)Air Flow (CFM)Pressure Drop (In. of Water)Air Flow (CFM)Pressure Drop (In. of Water)500 7.50.1011.00.15100022.50.2032.50.29150035.00.4151.00.60RF RADIATION - Avoid exposure to strong rf fields even at relatively low frequency. Absorption of rf energy by human tissue is dependent on frequency. Under 300 MHz most of the energy will pass completely through the human body with little attenuation or heating affect. Public health agencies are concerned with the hazard, and the published OSHA (Occu-pational Safety and Health Administration) or other local rec-ommendations to limit prolonged exposure of rf radiation should be followed. It is worth noting that some commer-cial dielectric heating units actually operate at frequencies as low as the 13 and 27 MHz bands.INTERELECTRODE CAPACITANCE - The actual internal inter-electrode capacitance of a tube is influenced by many vari-ables in most applications, such as stray capacitance to the chassis, capacitance added by the socket used, stray capaci-tance between tube terminals, and wiring effects. To control the actual capacitance values within the tube, as the key com-ponent involved, the industry and the Military Services use a standard test procedure as described in Electronic Industries Association Standard RS-191. This requires the use of special-ly constructed test fixtures, which effectively shield all external tube leads from each other and eliminates any capacitance reading to ‘ground’. The test is performed on a cold tube in a special shielded fixture.Other factors being equal, controlling internal tube ca-pacitance in this way normally assures good interchange-ability of tubes over a period of time, even when the tube may be made by different manufacturers. The capacitance values shown in the manufacturer’s technical data, or test specifications, normally are taken in accordance with Standard RS-191. The equipment designer is therefore cautioned to make allowance for the actual capacitance values which will exist in any normal application. Measurements should be taken with mounting which represents approximate final layout if capacitance values are highly significant in the design.Many Eimac power tubes such as this are specifically de-signed to generate or amplify radio frequency power. There may be a relatively strong rf field in the general proximity of the power and its associated circuitry - the more power involved the stronger the rf field. Proper en-closure design and efficient coupling of rf energy to the load will minimize the rf field in the vicinity of the power amplifier itself.HIGH VOLTAGE - The 3CX1500A7/8877 operates at volt-ages which can be deadly, and the equipment must be designed properly a nd opera ting preca utions must be followed. Equipment must be designed so that no one can come in contact with high voltages. All equipment must include sa fety enclosures for high-volta ge circuits and terminals, with interlock switches to open the prima-ry circuits of the power supplies and to discharge high-voltage ca pa citors whenever a ccess doors a re opened. Interlock switches must not be bypassed or “cheated” to allow operation with access doors open. Always remem-ber that HIGH VOLTAGE CAN KILL.HOT SURF ACES - Air-cooled surfaces and other parts of tubes can reach temperatures of several hundred de-grees C and cause serious burns if touched for several minutes after all power is removed.SPECIAL APPLICATIONS - If it is desired to operate this tube under conditions widely different from those given here, contact the Application Engineering Dept., CPI MPP Eimac Operation for information and recommenda-tions.3CX1500A7/88773CX1500A7/8877 .HIGH VOLTAGE – Normal operating voltages can be deadly. Remember the HIGH VOLTAGE CAN KILL. LOW-VOLTAGE HIGH-CURRENT CIRCUITS - Per-sonal jewelry, such as rings, should not be worn when working with filament contacts or connectors as a short circuit can produce very high current and melting, resulting in severe burns.RF RADIATION – Exposure to strong rf fields should be avoided, even at relatively low frequencies. CARDIAC PACEMAKERS MAY BE AFFECTED.HOT WATER – Water used to cool tubes may reach scalding temperatures. Touching or rupture of the cooling system can cause serious burns. HOT SURFACES – Surfaces of tubes can reach temperatures of several hundred°C and cause se-rious burns if touched for several minutes after all power is removed.MATERIALS COMPLIANCE - This product and package conforms to the conditions and limita-tions specified in 49CFR 173.424 for radioactive material, excepted package-instruments or ar-ticles, UN2910. In addition, this product and pack-age contains no beryllium oxide (BeO).OPERATING HAZARDSProper use and safe operating practices with respect to power tubes are the responsibility of equipment manu-facturers and users of such tubes.

MAX8887EZKXY中文资料

General DescriptionThe MAX8887/MAX8888 low-dropout linear regulators operate from a +2.5V to +5.5V input and deliver up to 300mA continuous (500mA pulsed) current. The MAX8887 is optimized for low-noise operation, while the MAX8888 includes an open-drain POK ouput flag. Both regulators feature exceptionally low 100mV dropout at 200mA. These devices are available in a variety of pre-set output voltages in the +1.5V to +3.3V range.An internal PMOS pass transistor allows the low 55µA supply current to remain independent of load, making these devices ideal for portable battery-powered equip-ment such as personal digital assistants (PDAs), cellu-lar phones, cordless phones, and notebook computers.Other features include a micropower shutdown mode,short-circuit protection, thermal shutdown protection,and an active-low open-drain power-OK (POK) output that indicates when the output is out of regulation.

The devices supply loads up to 300mA and are available in several fixed output voltages in the +1.5 to +3.3V range. The MAX8887 is optimized for low-noise operation, while the MAX8888 includes an open-drain POK output flag.As illustrated in F igure 1, the MAX8888 consists of a 1.25V reference, error amplifier, P-channel pass tran-sistor, and internal feedback voltage divider.Internal P-Channel Pass TransistorThe MAX8887/MAX8888 feature a 0.5ΩP-channel MOSF ET pass transistor. Unlike similar designs using PNP pass transistors, P-channel MOSF ETs require no base drive, which reduces quiescent current. PNP-based regulators also waste considerable current in dropout when the pass transistor saturates and use high base drive currents under large loads. The MAX8887/MAX8888 do not suffer from these problems and consume only 55µA of quiescent current under heavy loads as well as in dropout.Ouput Voltage SelectionThe MAX8887/MAX8888 are supplied with various fac-tory-set output voltages ranging from 1.5V to 3.3V. The part number ’s two-digit suffix identifies the nominal out-put voltage. F or example, the MAX8887EUK33 has a preset output voltage of 3.3V (see Ordering Infor-mation ).ShutdownDrive SHDN low to enter shutdown. During shutdown,the output is disconnected from the input and supply current drops to 0.1µA. When in shutdown, POK and OUT are driven low. SHDN can be pulled as high as 6V, regardless of the input and output voltages.Power-OK OutputThe power-OK output (POK) pulls low when OUT is less than 93% of the nominal regulation voltage. Once OUT exceeds 93% of the nominal voltage, POK goes high impedance. POK is an open-drain N-channel output.To obtain a logic level output, connect a pullup resistor from POK to OUT. A 100k Ωresistor works well for most applications. POK can be used as a power-on-reset (POR) signal to a microcontroller (µC) or to drive other logic. Adding a capacitor from POK to ground creates POK delay. When the MAX8887 is shut down, POK is held low independent of the output voltage. If unused,leave POK grounded or unconnected.Current LimitThe MAX8887/MAX8888 monitor and control the pass transistor ’s gate voltage, limiting the output current to0.8A (typ). This current limit is reduced to 500mA (typ)when the output voltage is below 93% of the nominal value to provide foldback current limiting.Thermal-Overload ProtectionThermal-overload protection limits total power dissipa-tion in the MAX8887/MAX8888. When the junction tem-perature exceeds T J =+170°C, a thermal sensor turns off the pass transistor, allowing the device to cool. The thermal sensor turns the pass transistor on again after the junction temperature cools by 20°C, resulting in a pulsed output during continuous thermal overload con-ditions. Thermal overload protection protects the MAX8887/MAX8888 in the event of fault conditions. For continuous operation, do not exceed the absolute maxi-mum junction-temperature rating of T J =+150°C.Operating Region and Power DissipationThe MAX8887/MAX8888’s maximum power dissipation depends on the thermal resistance of the IC package and circuit board. The temperature difference between the die junction and ambient air, and the rate of air flow.The power dissipated in the device is P = I OUT ✕(V IN -V OUT ). The maximum allowed power dissipation is 727mW or:P MAX = (T J(MAX)- T A ) / (θJC + θCA )where T J(MAX)-T A is the temperature difference between the MAX8887/MAX8888 die junction and the surrounding air; θJC is the thermal resistance from the junction to the case; and θCA is the thermal resistance from the case through PC board, copper traces, and other materials to the surrounding air.Refer to Figure 2 for the MAX8887/MAX888 valid oper-ating region.Noise ReductionF or the MAX8887 only, an external 0.01µF bypass capacitor at BP creates a lowpass filter for noise reduc-tion. The MAX8887 exhibits 42µV RMS of output voltage noise with C BP = 0.01µF and C OUT = 2.2µF (see Typical Operating Characteristics ).Applications InformationCapacitor Selection and RegulatorStabilityConnect a 2.2µF ceramic capacitor between IN and ground and a 2.2µF ceramic capacitor between OUT and ground. The input capacitor (C IN ) lowers the source impedance of the input supply. Reduce noise and improve load-transient response, stability, and power-supply rejection by using a larger ceramic out-put capacitor such as 4.7µF.The output capacitor ’s (C OUT ) equivalent series resis-tance (ESR) affects stability and output noise. Use out-M A X 8887/M A X 8888Low-Dropout, 300mA Linear Regulators in SOT236_______________________________________________________________________________________put capacitors with an ESR of 0.1Ωor less to ensure sta-bility and optimum transient response. Surface-mount ceramic capacitors have very low ESR and are com-monly available in values up to 10µF. Connect C IN and C OUT as close to the MAX8887/MAX8888 as possible to minimize the impact of PC board trace inductance.Noise, PSRR, and Transient ResponseThe MAX8887/MAX8888 are designed to operate with low dropout voltages and low quiescent currents in bat-tery-powered systems while still maintaining excellent noise, transient response, and AC rejection. See the Typica l Opera ting Cha ra cteristics for a plot of power-supply rejection ratio (PSRR) versus frequency. When operating from noisy sources, improved supply-noise rejection and transient response can be achieved by increasing the values of the input and output bypass capacitors and through passive filtering techniques.Input-Output (Dropout) VoltageA regulator ’s minimum input-to-output voltage differen-tial (dropout voltage) determines the lowest usable sup-ply voltage at which the output is regulated. In battery-powered systems, this determines the useful end-of-life battery voltage. The MAX8887/MAX8888 use a P-channel MOSF ET pass transistor. Its dropout volt-age is a function of drain-to-source on-resistance (R DS(ON)) multiplied by the load current (see Typical Operating Characteristics ).V DROPOUT = V IN - V OUT = R DS(ON)✕I OUTChip InformationTRANSISTOR COUNT: 620PROCESS: BiCMOSMAX8887/MAX8888Low-Dropout, 300mA Linear Regulators in SOT23_______________________________________________________________________________________7Figure 1.

MAX247/MAX248/MAX249 Control Pin ConfigurationsM A X 220–M A X 249_______________Detailed DescriptionThe MAX220–MAX249 contain four sections: dual charge-pump DC-DC voltage converters, RS-232 dri-vers, RS-232 receivers, and receiver and transmitter enable control inputs.Dual Charge-Pump Voltage ConverterThe MAX220–MAX249 have two internal charge-pumps that convert +5V to ±10V (unloaded) for RS-232 driver operation. The first converter uses capacitor C1 to dou-ble the +5V input to +10V on C3 at the V+ output. The second converter uses capacitor C2 to invert +10V to -10V on C4 at the V- output.A small amount of power may be drawn from the +10V (V+) and -10V (V-) outputs to power external circuitry (see the Typical Operating Characteristics section),except on the MAX225 and MAX245–MAX247, where these pins are not available. V+ and V- are not regulated,so the output voltage drops with increasing load current.Do not load V+ and V- to a point that violates the mini-mum ±5V EIA/TIA-232E driver output voltage when sourcing current from V+ and V- to external circuitry. When using the shutdown feature in the MAX222,MAX225, MAX230, MAX235, MAX236, MAX240,MAX241, and MAX245–MAX249, avoid using V+ and V-to power external circuitry. When these parts are shut down, V- falls to 0V, and V+ falls to +5V. For applica-tions where a +10V external supply is applied to the V+pin (instead of using the internal charge pump to gen-erate +10V), the C1 capacitor must not be installed and the SHDN pin must be tied to V CC . This is because V+is internally connected to V CC in shutdown mode.RS-232 DriversThe typical driver output voltage swing is ±8V when loaded with a nominal 5k ΩRS-232 receiver and V CC =+5V. Output swing is guaranteed to meet the EIA/TIA-232E and V.28 specification, which calls for ±5V mini-mum driver output levels under worst-case conditions.These include a minimum 3k Ωload, V CC = +4.5V, and maximum operating temperature. Unloaded driver out-put voltage ranges from (V+ -1.3V) to (V- +0.5V). Input thresholds are both TTL and CMOS compatible.The inputs of unused drivers can be left unconnected since 400k Ωinput pull-up resistors to V CC are built in (except for the MAX220). The pull-up resistors force the outputs of unused drivers low because all drivers invert.The internal input pull-up resistors typically source 12µA,except in shutdown mode where the pull-ups are dis-abled. Driver outputs turn off and enter a high-imped-ance state—where leakage current is typically microamperes (maximum 25µA)—when in shutdownmode, in three-state mode, or when device power is removed. Outputs can be driven to ±15V. The power-supply current typically drops to 8µA in shutdown mode.The MAX220 does not have pull-up resistors to force the ouputs of the unused drivers low. Connect unused inputs to GND or V CC .The MAX239 has a receiver three-state control line, and the MAX223, MAX225, MAX235, MAX236, MAX240,and MAX241 have both a receiver three-state control line and a low-power shutdown control. Table 2 shows the effects of the shutdown control and receiver three-state control on the receiver outputs.The receiver TTL/CMOS outputs are in a high-imped-ance, three-state mode whenever the three-state enable line is high (for the MAX225/MAX235/MAX236/MAX239–MAX241), and are also high-impedance whenever the shutdown control line is high.When in low-power shutdown mode, the driver outputs are turned off and their leakage current is less than 1µA with the driver output pulled to ground. The driver output leakage remains less than 1µA, even if the transmitter output is backdriven between 0V and (V CC + 6V). Below -0.5V, the transmitter is diode clamped to ground with 1k Ωseries impedance. The transmitter is also zener clamped to approximately V CC + 6V, with a series impedance of 1k Ω.The driver output slew rate is limited to less than 30V/µs as required by the EIA/TIA-232E and V.28 specifica-tions. Typical slew rates are 24V/µs unloaded and 10V/µs loaded with 3Ωand 2500pF.RS-232 ReceiversEIA/TIA-232E and V.28 specifications define a voltage level greater than 3V as a logic 0, so all receivers invert.Input thresholds are set at 0.8V and 2.4V, so receivers respond to TTL level inputs as well as EIA/TIA-232E and V.28 levels.The receiver inputs withstand an input overvoltage up to ±25V and provide input terminating resistors withDrivers/Receivers 14Table 2. Three-State Control of ReceiversMAX220–MAX249Drivers/Receivers______________________________________________________________________________________15nominal 5k Ωvalues. The receivers implement Type 1interpretation of the fault conditions of V.28 and EIA/TIA-232E.The receiver input hysteresis is typically 0.5V with a guaranteed minimum of 0.2V. This produces clear out-put transitions with slow-moving input signals, even with moderate amounts of noise and ringing. The receiver propagation delay is typically 600ns and is independent of input swing direction.Low-Power Receive ModeThe low-power receive-mode feature of the MAX223,MAX242, and MAX245–MAX249 puts the IC into shut-down mode but still allows it to receive information. This is important for applications where systems are periodi-cally awakened to look for activity. Using low-power receive mode, the system can still receive a signal that will activate it on command and prepare it for communi-cation at faster data rates. This operation conserves system power.Negative Threshold—MAX243The MAX243 is pin compatible with the MAX232A, differ-ing only in that RS-232 cable fault protection is removed on one of the two receiver inputs. This means that control lines such as CTS and RTS can either be driven or left floating without interrupting communication. Different cables are not needed to interface with different pieces of equipment.The input threshold of the receiver without cable fault protection is -0.8V rather than +1.4V. Its output goes positive only if the input is connected to a control line that is actively driven negative. If not driven, it defaults to the 0 or “OK to send” state. Normally‚ the MAX243’s other receiver (+1.4V threshold) is used for the data line (TD or RD)‚ while the negative threshold receiver is con-nected to the control line (DTR‚ DTS‚ CTS‚ RTS, etc.). Other members of the RS-232 family implement the optional cable fault protection as specified by EIA/TIA-232E specifications. This means a receiver output goes high whenever its input is driven negative‚ left floating‚or shorted to ground. The high output tells the serial communications IC to stop sending data. To avoid this‚the control lines must either be driven or connected with jumpers to an appropriate positive voltage level.Shutdown—MAX222–MAX242On the MAX222‚ MAX235‚ MAX236‚ MAX240‚ and MAX241‚ all receivers are disabled during shutdown.On the MAX223 and MAX242‚ two receivers continue to operate in a reduced power mode when the chip is in shutdown. Under these conditions‚ the propagation delay increases to about 2.5µs for a high-to-low input transition. When in shutdown, the receiver acts as a CMOS inverter with no hysteresis. The MAX223 and MAX242 also have a receiver output enable input (EN for the MAX242 and EN for the MAX223) that allows receiver output control independent of SHDN (SHDN for MAX241). With all other devices‚ SHDN (SH DN for MAX241) also disables the receiver outputs.The MAX225 provides five transmitters and five receivers‚ while the MAX245 provides ten receivers and eight transmitters. Both devices have separate receiver and transmitter-enable controls. The charge pumps turn off and the devices shut down when a logic high is applied to the ENT input. In this state, the supply cur-rent drops to less than 25µA and the receivers continue to operate in a low-power receive mode. Driver outputs enter a high-impedance state (three-state mode). On the MAX225‚ all five receivers are controlled by the ENR input. On the MAX245‚ eight of the receiver out-puts are controlled by the ENR input‚ while the remain-ing two receivers (RA5 and RB5) are always active.RA1–RA4 and RB1–RB4 are put in a three-state mode when ENR is a logic high.Receiver and Transmitter EnableControl InputsThe MAX225 and MAX245–MAX249 feature transmitter and receiver enable controls.The receivers have three modes of operation: full-speed receive (normal active)‚ three-state (disabled)‚ and low-power receive (enabled receivers continue to function at lower data rates). The receiver enable inputs control the full-speed receive and three-state modes. The transmitters have two modes of operation: full-speed transmit (normal active) and three-state (disabled). The transmitter enable inputs also control the shutdown mode. The device enters shutdown mode when all transmitters are disabled. Enabled receivers function in the low-power receive mode when in shutdown.M A X 220–M A X 249Tables 1a–1d define the control states. The MAX244has no control pins and is not included in these tables. The MAX246 has ten receivers and eight drivers with two control pins, each controlling one side of the device. A logic high at the A-side control input (ENA )causes the four A-side receivers and drivers to go into a three-state mode. Similarly, the B-side control input (ENB ) causes the four B-side drivers and receivers to go into a three-state mode. As in the MAX245, one A-side and one B-side receiver (RA5 and RB5) remain active at all times. The entire device is put into shut-down mode when both the A and B sides are disabled (ENA = ENB = +5V).The MAX247 provides nine receivers and eight drivers with four control pins. The ENRA and ENRB receiver enable inputs each control four receiver outputs. The ENTA and ENTB transmitter enable inputs each control four drivers. The ninth receiver (RB5) is always active.The device enters shutdown mode with a logic high on both ENTA and ENTB .The MAX248 provides eight receivers and eight drivers with four control pins. The ENRA and ENRB receiver enable inputs each control four receiver outputs. The ENTA and ENTB transmitter enable inputs control four drivers each. This part does not have an always-active receiver. The device enters shutdown mode and trans-mitters go into a three-state mode with a logic high on both ENTA and ENTB .The MAX249 provides ten receivers and six drivers with four control pins. The ENRA and ENRB receiver enable inputs each control five receiver outputs. The ENTA and ENTB transmitter enable inputs control three dri-vers each. There is no always-active receiver. The device enters shutdown mode and transmitters go into a three-state mode with a logic high on both ENTA and ENTB . In shutdown mode, active receivers operate in a low-power receive mode at data rates up to 20kbits/sec.__________Applications InformationFigures 5 through 25 show pin configurations and typi-cal operating circuits. In applications that are sensitive to power-supply noise, V CC should be decoupled to ground with a capacitor of the same value as C1 and C2 connected as close as possible to the device.Drivers/Receivers16______________________________________________________________________________________。

REINVENTED.The MAX-700B/C Series is the first tablet-inspired OTDR line that is handy, lightweight and rugged enough for any outside plant environment. With a 7-inch, outdoor-enhanced touchscreen–the most efficient handheld display in the industry–it delivers an unprecedented user experience. Its intuitive Windows-like GUI ensures a fast learning curve. Plus, its new and improved OTDR 2 environment offers icon-based functions, instant boot-up, automatic macrobend finders as well as improved auto and real-time modes. The Max-700B/C Series is a line of genuine high-performance OTDRs from the world’s leading manufacturer. It delivers EXFO’s tried and true OTDR quality and accuracy along with the best optical performance for right-first-time results, every time.The amazing 12-hour battery life will never let a technician down, and the plug-and-play hardware options, like the VFL, power meter and USB tools, make every technician’s job easier.Most importantly, the Max-700B/C Series is finally bringing the iOLM, an intelligent OTDR-based application, to the handheld market. This advanced software turns even the most complex trace analysis into a simple, one-touch task.Ultimately, the Max-700B/C Series is small enough to fit in your hand and big enough to fit all your needs!THE ENTRY-LEVEL SOLUTION DESIGNED FOR ALL YOUR TESTING NEEDSThe MAX-715B OTDR/iOLM is optimized for the point-to-point testing and troubleshooting of FTTx architectures, and is ideal for testing short fibers (e.g., inside a CO environment or at FTTA/DAS network installations).Other models available:›MAX-720C LAN/WAN Access OTDR—optimized for multimode and singlemode access network installation and maintenance›MAX-730C PON/Metro OTDR—optimized for FTTx/MDU and short metro ﬁ ber deployments and troubleshootingLOOKING FOR ICON-BASED MAPPING?Linear View (Included on All EXFO OTDRs)Available on our OTDRs since 2006, linear view simplifies interpretation of an OTDR trace by displaying icons in a linear way for each wavelength. This view converts the graph data points obtained from a traditional single pulse trace into reflective or non-reflective icons. With applied pass/fail thresholds, it becomes easier to pinpoint faults on your link.This improved linear view offers you the flexibility to displayboth the OTDR graph and its linear view without having toperform a toggle to analyze your fiber link.Although this linear view simplifies OTDR interpretationof a single pulse-width trace, the user must still set theOTDR parameters. In addition, multiple traces must oftenbe performed in order to fully characterize the fiber links.See the section below to learn about how the iOLM canperform this automatically and with more accurate results.iOLM—REMOVING THE COMPLEXITY FROM OTDR TESTINGDynamic multipulse acquisitionIntelligent trace analysisAll results combined into a single link viewComprehensive diagnosisTurning traditional OTDR testing into clear, automated, first-time-right results for technicians iOLM ONLYOTDR TESTING COMES WITH ITS LOAD OF ans 2XXiOLM FEATURES VALUE PACKIn addition to the standard iOLM feature set, you can select added-value features as part of the packages.

In either case, installation is a snap, and can be performed by the user without the need for any software update. Optical Power MeterA high-level power meter (GeX) that can measure up to 27 dBm, the highest in the industry. This is essential for hybrid fiber-coaxial (HFC) networks or high-power signals. If used with an auto-lambda/auto-switching compatible light source, the power meter automatically synchronizes on the same wavelength, thus avoiding any risk of mismatched measurement.›Extensive range of connectors›Auto-lambda and auto-switching›Offers measurement storage and reporting›Seven standard calibrated wavelengthsVisual Fault Locator (VFL)The plug-and-play VFL easily identifies breaks, bends, faulty connectors and splices, in addition to other causes of signal loss. This basic, yet essential troubleshooting tool should be part of every field technician’s toolbox. The VFL visually locates and detects faults over distances of up to 5 km by creating a bright-red glow at the exact location of the fault on singlemode or multimode fibers (available with the Optical Power Meter only).FIBER CONNECTOR INSPECTION AND CERTIFICATION–THE ESSENTIAL FIRST STEP BEFORE ANY OTDR TESTINGTaking the time to properly inspect a fiber-optic connector using an EXFO fiber inspectionprobe can prevent a host of issues from arising further down the line, thus saving you time,money and trouble.

MAX266中文数据手册

MAX266中文数据手册MAX266/265中文数据手册By Hi_Cracker @whu引脚电阻可编程通用高效滤波器-----MAX266/265General Description和MAX265是高效的容滤波器，专门设计用于需要高精度滤波的应用MAX266场合。

内置了两个独立的滤波模块，可以配置成低通，高通，带通，带阻，全通滤波器。

中心频率或者截止频率的控制需要外接电阻以及6 Pin-Strapped 的输入特性来编程实现，然而，Q值仅用电阻连接实现。

各种各样类型的滤波器都可以实现（巴特沃斯，切比雪夫，椭圆滤波器等等）。

内部集成了两个运算放大器。

MAX265可以将中心/截止频率可以最高调到40Khz，然而，MAX266，通过使用一个低范围的fclk/fo比例系数，可以将fos 调到140Khz。

4MHZ系统时钟，可以通过一个晶振或是额外的源获得。

滤波器的操作电压为从±2.37v到±6.3v或者+5V的单电源供电。

Application：声纳电子设备Anti-Aliasing 滤波器数字信号处理震动音频分析远程通信测试仪器Features滤波器参数设置软件化256bit的频率控制字电阻调整Q值和fo140Khz频率调节范围±5V或者单电源﹢5V操作电压Introduction每个MAX266/265都包含的两个可配置滤波器模块已经显示在数据手册前面的功能框图上。

fclk/fo编程输入（F0-F5）被两个滤波模块共用,然而，每个部分的fo仍然受到各自外接电阻的独立调节。

各个模块的的Q值也是受到各自的外接电阻的独立调节的。

MAX266使用比MAX265更低范围的取样比率（fclk/fo），这样就可以产生更高的信号带宽以及fo的可编程范围。

降低fclk/fo产生的影响主要就是比MAX265的滤波器参数的连续性稍微差了一些，但是这些不同可以通过使用图23所示的图形或是美信得滤波器软件来补偿。
