General DescriptionThe MAX6161–MAX6168 are precision, low-dropout,micropower voltage references. These three-terminal devices operate with an input voltage range from (V OUT + 200mV) to 12.6V and are available with output volt-age options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V,4.5V, and 5V. They feature a proprietary curvature-cor-rection circuit and laser-trimmed thin-film resistors that result in a very low temperature coefficient of 5ppm/°C (max) and an initial accuracy of ±2mV (max).Specifications apply to the extended temperature range (-40°C to +85°C).The MAX6161–MAX6168 typically draw only 100µA of supply current and can source 5mA (4mA for MAX6161) or sink 2mA of load current. Unlike conven-tional shunt-mode (two-terminal) references that waste supply current and require an external resistor, these devices offer a supply current that is virtually indepen-dent of the supply voltage (8µA/V variation) and do not require an external resistor. Additionally, the internally compensated devices do not require an external com-pensation capacitor. Eliminating the external compen-sation capacitor saves valuable board area in space-critical applications. A low-dropout voltage and a supply-independent, ultra-low supply current make these devices ideal for battery-operated, high-perfor-mance, low-voltage systems.The MAX6161–MAX6168 are available in 8-pin SO packages.________________________ApplicationsAnalog-to-Digital Converters (ADCs)Portable Battery-Powered Systems Notebook Computers PDAs, GPS, DMMs Cellular PhonesPrecision +3V/+5V Systems____________________________Features♦±2mV (max) Initial Accuracy♦5ppm/°C (max) Temperature Coefficient ♦5mA Source Current at 0.9mV/mA ♦2mA Sink Current at 2.5mV/mA ♦Stable with 1µF Capacitive Loads ♦No External Capacitor Required ♦100µA (typ) Quiescent Supply Current ♦200mV (max) Dropout at 1mA Load Current ♦Output Voltage Options: 1.25V, 1.8V, 2.048V, 2.5V,3V, 4.096V, 4.5V, 5V19-1650; Rev 3; 8/05MAX6161–MAX6168Precision, Micropower, Low-Dropout, High-Output-Current, SO-8 Voltage References________________________________________________________________Maxim Integrated Products 1___________________Pin Configuration*Insert the code for the desired initial accuracy and temperature coefficient (from the Selector Guide) in the blank to complete the part number.Typical Operating Circuit and Selector Guide appear at end of data sheet.Ordering InformationFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 6161–M A X 6168Precision, Micropower, Low-Dropout, High-Output-Current, SO-8 Voltage References 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Locate the capacitor as close to IN as possible. When transient performance is less important, no capacitor is necessary.Output/Load CapacitanceDevices in the MAX6161 family do not require an output capacitor for frequency stability. In applications where the load or the supply can experience step changes,an output capacitor of at least 0.1µF will reduce the amount of overshoot (undershoot) and improve the cir-cuit’s transient response. Many applications do not require an external capacitor, and the MAX6161 family can offer a significant advantage in applications when board space is critical.Supply CurrentThe quiescent supply current of the series-mode MAX6161 family is typically 100µA and is virtually inde-pendent of the supply voltage, with only an 8µA/V (max) variation with supply voltage. Unlike series refer-ences, shunt-mode references operate with a series resistor connected to the power supply. The quiescent current of a shunt-mode reference is thus a function of the input voltage. Additionally, shunt-mode references have to be biased at the maximum expected load cur-rent, even if the load current is not present at the time.In the MAX6161 family, the load current is drawn from the input voltage only when required, so supply current is not wasted and efficiency is maximized at all input voltages. This improved efficiency reduces power dissi-pation and extends battery life.When the supply voltage is below the minimum speci-fied input voltage (as during turn-on), the devices can draw up to 400µA beyond the nominal supply current.The input voltage source must be capable of providing this current to ensure reliable turn-on.Output Voltage HysteresisOutput voltage hysteresis is the change in the input voltage at T A = +25°C before and after the device is cycled over its entire operating temperature range.Hysteresis is caused by differential package stress appearing across the bandgap core transistors. The typical temperature hysteresis value is 125ppm.Turn-On TimeThese devices typically turn on and settle to within 0.1% of their final value in 50µs to 300µs, depending on the output voltage (see electrical table of part used).The turn-on time can increase up to 1.5ms with the device operating at the minimum dropout voltage and the maximum load.Typical Operating Circuit__________________________Chip Information TRANSISTOR COUNT: 117PROCESS: BiCMOSPin DescriptionPIN NAME FUNCTIONNo Connection.

Energy-friendly.Rev. 1.00 | 33.3.4 Matching Network for 2.4 GHzThe BRD4161A Radio Board incorporates a 2.4 GHz matching network which connects the 2.4 GHz TRX pin of the EFR32MG12 to the one on-board printed Inverted-F antenna. The component values were optimized for the 2.4 GHz band RF performace and current con-sumption with 19 dBm output power.For detailed description of the matching network, see Chapter 4.2.1 Description of the 2.4 GHz RF Matching.3.3.5 Inverted-F AntennaThe BRD4161A Radio Board includes a printed Inverted-F antenna (IFA) tuned to have close to 50 Ohm impedance at the 2.4 GHz band.For detailed description of the antenna see Chapter 4.5 Inverted-F Antenna.3.3.6 UFL ConnectorTo be able to perform conducted measurements, Silicon Labs added an UFL connector to the Radio Board. The connector allows an external 50 Ohm cable or antenna to be connected during design verification or testing.Note: By default the output of the matching network is connected to the printed Inverted-F antenna by a series component. It can be connected to the UFL connector as well through a series 0 Ohm resistor which is not mounted by default. For conducted measurements through the UFL connector the series component to the antenna should be removed and the 0 Ohm resistor should be mounted (see Chapter 4.2 Schematic of the RF Matching Network for further details).3.3.7 Radio Board ConnectorsTwo dual-row, 0.05” pitch polarized connectors make up the EFR32MG Radio Board interface to the Wireless Starter Kit Mainboard. For more information on the pin mapping between the EFR32MG12P432F1024GL125 and the Radio Board Connector, refer to Chapter 2.2 Radio Board Connector Pin Associations.3.3.8 Capacitive Touch SliderThe touch slider (T2) utilizes the capacitive touch capability of the Capacitance Sense Module of the EFR32MG12.

RF Section4.1 IntroductionThis section gives a short introduction to the RF section of the BRD4161A.4.2 Schematic of the RF Matching NetworkThe schematic of the RF section of the BRD4161A Radio Board is shown in the following figure.2.4 GHz Matching 2.4 GHz RF OutputSelection & Inverted-F AntennaFigure 4.1. Schematic of the RF Section of the BRD4161A4.2.1 Description of the 2.4 GHz RF MatchingThe 2.4 GHz matching connects the 2G4RF_IOP pin to the on-board printed Inverted-F Antenna. The 2G4RF_ION pin is connected to ground. For higher output powers (13 dBm and above), besides the impedance matching circuitry, it is recommended to use additional harmonic filtering as well at the RF output. The targeted output power of the BRD4161A board is 19 dBm. Therefore, the RF output of the IC is connected to the antenna through a four-element impedance matching and harmonic filter circuitry.For conducted measurements the output of the matching network can also be connected to the UFL connector by removing the series R1 component between the antenna and the output of the matching and adding a 0 Ohm resistor to the R2 resistor position between the output of the matching and the UFL connector.4.3 RF Section Power SupplyOn the BRD4161A Radio Board the power supply pins of the RF section (RFVDD, PAVDD) are directly connected to the output of the on-chip DC-DC converter. This way, by default, the DC-DC converter provides 1.8 V for the entire RF section (for details, see the sche-matic of the BRD4161A).4.4 Bill of Materials for the 2.4 GHz MatchingThe Bill of Materials of the 2.4 GHz matching network of the BRD4161A Radio Board is shown in the following table.| Smart. Connected. Energy-friendly.Rev. 1.00 | 5Table 4.1. Bill of Materials for the BRD4161A 2.4GHz RF Matching Network4.5 Inverted-F AntennaThe BRD4161A Radio Board includes an on-board printed Inverted-F Antenna tuned for the 2.4 GHz band. Due to the design restric-tions of the Radio Board, the input of the antenna and the output of the matching network can't be placed directly next to each other. As a result, a 50 Ohm transmission line was necessary to connect them. With the actual line length the impedance of the antenna at the double-harmonic frequency is transformed closer to a "critical load impedance range" resulting in the radiated level of the harmonic increases.To reduce the harmonic radiation a tuning component was used between the matching network output and the antenna input. For the actual Radio Board design (with the actual transmission line length) a small value inductor was used (instead of the R1 resistor with value of 1.8 nH) to transform the impedance at the double-frequency harmonic away from the critical region while keeping the impe-dance at the funamental close to 50 Ohm. With this the suppression of the radiated double-frequency harmonic increases by approxi-mately 3-4 dB. The resulting impedance and reflection measured at the output of the matcing network are shown in the following figure. As it can be observed the impedance is close to 50 Ohm (the reflection is better than -10 dB) for the entire 2.4 GHz band.Figure 4.2. Impedance and Reflection of the Inverted-F Antenna of the BRD4161A Board Measured from the Matching Output Note: The same value and type of 1.8 nH inductor was used as the one in the matching network (L1). | Smart.

BRD4161A Bottom ViewMechanical DetailsRev. 1.00 | 7EMC Compliance 6. EMC Compliance6.1 IntroductionCompliance of the fundamental and harmonic levels is tested against the following standards:• 2.4 GHz:•ETSI EN 300-328•FCC 15.2476.2 EMC Regulations for 2.4 GHz6.2.1 ETSI EN 300-328 Emission Limits for the 2400-2483.5 MHz BandBased on ETSI EN 300-328 the allowed maximum fundamental power for the 2400-2483.5 MHz band is 20 dBm EIRP. For the unwan-ted emissions in the 1 GHz to 12.75 GHz domain the specified limit is -30 dBm EIRP.6.2.2 FCC15.247 Emission Limits for the 2400-2483.5 MHz BandFCC 15.247 allows conducted output power up to 1 Watt (30 dBm) in the 2400-2483.5 MHz band. For spurious emmissions the limit is -20 dBc based on either conducted or radiated measurement, if the emission is not in a restricted band. The restricted bands are speci-fied in FCC 15.205. In these bands the spurious emission levels must meet the levels set out in FCC 15.209. In the range from 960 MHz to the frequency of the 5th harmonic it is defined as 0.5 mV/m at 3 m distance (equals to -41.2 dBm in EIRP).Additionally, for spurious frequencies above 1 GHz, FCC 15.35 allows duty-cycle relaxation to the regulatory limits. For the EmberZNet PRO the relaxation is 3.6 dB. Therefore, the -41.2 dBm limit can be modified to -37.6 dBm.If operating in the 2400-2483.5 MHz band the 2nd, 3rd and 5th harmonics can fall into restricted bands. As a result, for those the -37.6 dBm limit should be applied. For the 4th harmonic the -20 dBc limit should be applied.6.2.3 Applied Emission Limits for the 2.4 GHz BandThe above ETSI limits are applied both for conducted and radiated measurements.The FCC restricted band limits are radiated limits only. Besides that, Silicon Labs applies those to the conducted spectrum i.e., it is assumed that, in case of a custom board, an antenna is used which has 0 dB gain at the fundamental and the harmonic frequencies. In that theoretical case, based on the conducted measurement, the compliance with the radiated limits can be estimated.The overall applied limits are shown in the table below.Table 6.1. Applied Limits for Spurious Emissions for the 2.4 GHz Band | Smart. Connected. Energy-friendly.Rev. 1.00 | 87. RF Performance7.1 Conducted Power MeasurementsDuring measurements, the EFR32MG Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the Radio Board was 3.3 V.7.1.1 Conducted Measurements in the 2.4 GHz bandThe BRD4161A board was connected directly to a Spectrum Analyzer through its UFL connector (the R1 component was removed and a 0 Ohm resistor was soldered to the R2 resistor position). During measurements, the voltage supply for the board was 3.3 V provided by the mainboard. The supply for the radio (RFVDD) was 1.8 V provided by the on-chip DC-DC converter, the supply for the power amplifier (PAVDD) was 3.3 V (for details, see the schematic of the BRD4161A). The transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to 19 dBm.The typical output spectrum is shown in the following figure.Figure 7.1. Typical Output Spectrum of the BRD4161AAs it can be observed, the fundamental is slightly lower than 19 dBm limit and the strongest unwanted emission is the double-frequency harmonic and it is under the -37.6 dBm applied limit.Note: The conducted measurement is performed by connecting the on-board UFL connector to a Spectrum Analyzer through an SMA Conversion Adapter (P/N: HRMJ-U.FLP(40)). This connection itself introduces approximately 0.3 dB insertion loss.RF PerformanceRev. 1.00 | 97.2 Radiated Power MeasurementsDuring measurements, the EFR32MG Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the Radio Board was 3.3 V. The radiated power was measured in an antenna chamber by rotating the DUT 360degrees with horizontal and vertical reference antenna polarizations in the XY , XZ and YZ cuts. The measurement axes are shown inthe figure below.Figure 7.2. DUT: Radio Board with the Wireless Starter Kit Mainboard (Illustration)Note: The radiated measurement results presented in this document were recorded in an unlicensed antenna chamber. Also the radi-ated power levels may change depending on the actual application (PCB size, used antenna, and so on). Therefore, the absolute levels and margins of the final application are recommended to be verified in a licensed EMC testhouse.7.2.1 Radiated Measurements in the 2.4 GHz bandFor the transmitter antenna the on-board printed Inverted-F antenna of the BRD4161A board was used (the R1 component was moun-ted). During measurements, the board was attached to a Wireless Starter Kit Mainboard (BRD4001 (Rev. A02) ) which was supplied through USB. During the measurements the voltage supply for the board was 3.3 V provided by the mainboard. The supply for the radio (RFVDD) was 1.8 V provided by the on-chip DC-DC converter, the supply for the power amplifier (PAVDD) was 3.3 V (for details, see the schematic of the BRD4161A). The transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to 19 dBm based on the conducted measurement.The results are shown in the table below.Table 7.1. Maximums of the measured radiated powers in EIRP [dBm]As it can be observed, thanks to the high gain of the Inverted-F antenna, the level of the fundamental is higher than 19 dBm. The stron-gest harmonic is the double-frequency one and thanks to the additional suppression provided by the instead of the R1 resistor its level is under -50 dBm.RF PerformanceEMC Compliance Recommendations 8. EMC Compliance Recommendations8.1 Recommendations for 2.4 GHz ETSI EN 300-328 complianceAs it was shown in the previous chapter, the radiated power of the fundamental of the BRD4161A Mighty Gecko Radio Board complies with the 20 dBm limit of the ETSI EN 300-328 in case of the conducted measurement but due to the high antenna gain the radiated power is higher than the limit by 2 dB. In order to comply, the output power should be reduced (with different antennas, depending on the gain of the used antenna, the necessary reduction can be different). The harmonic emissions are under the -30 dBm limit. Although the BRD4161A Radio Board has an option for mounting a shielding can, that is not required for the compliance.8.2 Recommendations for 2.4 GHz FCC 15.247 complianceAs it was shown in the previous chapter, the radiated power of the fundamental of the BRD4161A Mighty Gecko Radio Board complies with the 30 dBm limit of the FCC 15.247. The harmonic emissions are under the -37.6 dBm applied limit both in case of the conducted and the radiated measurements. Although the BRD4161A Radio Board has an option for mounting a shielding can, that is not required for the compliance.Document Revision History 9. Document Revision HistoryTable 9.1.

MAX4533CAP中文资料

General DescriptionThe MAX4533 quad, single-pole/double-throw (SPDT),fault-protected analog switch is pin-compatible with the industry-standard MAX333 and MAX333A. The MAX4533features fault-protected inputs and Rail-to-Rail ®signal handling. The normally open (NO_ ) and normally closed (NC_ ) terminals are protected from overvoltage faults up to ±25V with power on and up to ±40V with power off.During a fault condition, NO_ and NC_ become high impedance with only nanoamperes of leakage current flowing to the source. In addition, the output (COM_)clamps to the appropriate polarity supply rail and pro-vides up to ±10mA of load current. This ensures unam-biguous rail-to-rail outputs when a fault occurs.The MAX4533 operates from dual ±4.5V to ±18V power supplies or a single +9V to +36V supply. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±15V supplies or a +12V supply. On-resistance is 175Ωmax and is matched between switches to 10Ωmax. The off-leakage current is only 0.5nA at T A =+25°C and 10nA at T A =+85°C.ApplicationsRedundant/Backup Systems Portable Instruments Test EquipmentData-Acquisition Communications Systems SystemsIndustrial and Process ControlAvionics SystemsFeatureso Rail-to-Rail Signal Handlingo ±40V Fault Protection with Power Off±25V Fault Protection with ±15V Supplies o All Switches Off with Power Offo No Power-Supply Sequencing Required During Power-Up or Power-Down o Output Clamped to Appropriate Supply Voltage During Fault Condition—No Transition Glitch o 1k Ω(typ) Output Clamp Resistance During Overvoltage o 175Ω(max) Signal Paths with ±15V Supplies o 20ns (typ) Fault Response Time o ±4.5V to ±18V Dual Supplies +9V to +36V Single Supplyo Pin-Compatible with Industry-Standard MAX333/MAX333Ao TTL/CMOS-Compatible Logic Inputs with ±15V or Single +9V to +15V SuppliesMAX4533†Quad, Rail-to-Rail, Fault-Protected,SPDT Analog Switch________________________________________________________________Maxim Integrated Products 1Typical Operating Circuit19-1452; Rev 1; 10/99Pin Configuration/Functional DiagramOrdering InformationRail-to-Rail is a registered trademark of Nippon Motorola, Ltd.†Patent PendingFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 4533Quad, Rail-to-Rail, Fault-Protected,SPDT Analog SwitchABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS —Dual Supplies(V+ = +15V, V- = -15V, T A = T MIN to T MAX , unless otherwise noted.

Traditional fault-pro-tected switches are constructed using three-series CMOS devices. This combination produces good fault protection but fairly high on-resistance when the signals are within about 3V of each supply rail. These series devices are not capable of handling signals up to the power-supply rails.The MAX4533 differs considerably from traditional fault-protected switches, with three advantages. First, it is constructed with two parallel FETs, allowing very low on-resistance when the switch is on. Second, they allow signals on the NC_ or NO_ pins that are within or slightlybeyond the supply rails to be passed through the switch to the COM_ terminal, allowing rail-to-rail signal opera-tion. Third, when a signal on NC_ or NO_ exceeds the supply rails by about 150mV (a fault condition), the volt-age on COM_ is limited to the appropriate polarity sup-ply voltage. Operation is identical for both fault polarities. The fault-protection extends to ±25V with power on and ±40V with power off.The MAX4533 has a parallel N-channel and P-channel MOSFET switch configuration with input voltage sensors.The simplified internal structure is shown in Figure 1. The parallel N1 and P1 MOSFETs form the switch element.N3 and P3 are sensor elements to sample the input volt-age and compare it against the power-supply rails.*When the voltage on NO_ or NC_ does not exceed V+ or V-, NO_ (or NC_) and COM_ pins are bidirectional.During normal operation of a conducting channel, N1and P1 remain on with a typical 125Ωon-resistance between NO_ (or NC_) and COM_. If the input voltage exceeds either supply rail by about 150mV, the parallel combination switches (N1, P1) are forced off through the driver and sensing circuitries. At the same time, the output (COM_ ) is clamped to the appropriate supply rail by the clamp circuitries (N2, P2). Two clamp circuits limit the output voltage to the supply voltages.For simplicity, Figure 1 shows only one side of the SPDT switch configuration. The complete circuit is composed of two channels with their outputs connected.Normal OperationTwo comparators continuously compare the voltage on the NO_ (or NC_ ) pin with V+ and V- supply voltages.When the signal on NO_ (or NC_ ) is between V+ and V-, the switch behaves normally, with FETs N1 and P1turning on and off in response to NO_ (or NC_) signals (Figure 1). For any voltage between the supply rails,the switch is bidirectional; therefore, COM_ and NC_(or NO_ ) are interchangeable. Only NO_ and NC_ can be exposed to overvoltages beyond the supply range and within the specified breakdown limits of the device.Fault ConditionThe MAX4533 protects devices connected to its output (COM_) through its unique fault-protection circuitry.When the input voltage is raised above either supply rail, the internal sense and comparator circuitries (N3and N-channel driver or P3 and P-channel driver) dis-connect the output (COM_) from the input (Figure 1).If the switch driven above the supply rail has an on state, the clamp circuitries (N2 or P2) connect the out-put to the appropriate supply rail. Table 1 summarizes the MAX4533’s operation under normal and fault condi-tions. Row 5 shows a negative fault condition when the supplies are on. It shows that with supplies of ±15V, if the input voltage is between -15V and -25V, the output (COM_) clamps to the negative supply rail of -15V.With this technique, the SPDT switch is capable of with-standing a worse-case condition of opposite fault polar-ities at its inputs.Transient Fault ConditionWhen a fast rising or falling transient on NO_ (or NC_)exceeds V+ or V-, the output (COM_) follows the input (IN_) to the supply rail by only a few nanoseconds. This delay is due to the switch on-resistance and circuit capacitance to ground. However, when the input tran-sient returns to within the supply rails there is a longer recovery time. For positive faults, the recovery time is typically 2.5µs. For negative faults, the recovery time is typically 1.3µs. These values depend on the COM_ out-put resistance and capacitance. The delays are not dependent on the fault amplitude. Higher COM_ output resistance and capacitance increase the recovery times.Fault Protection, Voltage, and Power OffThe maximum fault voltage on the NO_ or NC_ pins is ±40V from ground when the power is off. With ±15V sup-ply voltages, the highest voltage on NO_ (or NC_) can be +25V, and the lowest voltage on NO_ (or NC_) can be -25V. Exceeding these limits can damage the chip.IN_ Logic-Level ThresholdsThe logic-level thresholds are TTL/CMOS-compatible when V+ is +15V. Raising V+ increases the threshold slightly; when V+ reaches +25V, the level threshold is 2.8V—higher than the TTL output high-level minimum of 2.4V, but still compatible with CMOS outputs (see the Typical Operating Characteristics ).Increasing V- has no effect on the logic-level thresh-olds, but it does increase the gate-drive voltage to the signal FETs, reducing their on-resistance.MAX4533Quad, Rail-to-Rail, Fault-Protected,SPDT Analog Switch_______________________________________________________________________________________9Figure 1. Simplified Internal StructureFailure ModesThe MAX4533 is not a lightning arrester or surge pro-tector. Exceeding the fault-protection voltage limits on NO_ or NC_, even for very short periods, can cause the device to fail.Applications InformationGroundThere is no connection between the analog signal paths and GND. The analog signal paths consist of an N-channel and P-channel MOSFET with their sources and drains paralleled and their gates driven out of phase to V+ and V- by the logic-level translators.V+ and GND power the internal logic and logic-level translators and set the input logic thresholds. The logic-level translators convert the logic levels to switched V+and V- signals to drive the gates of the switches. Thisdrive signal is the only connection between the power supplies and the analog signals. GND, IN_, and COM_have ESD protection diodes to V+ and V-.Supply Current ReductionWhen the logic signals are driven rail-to-rail from 0 to +12V or -15V to +15V, the supply current reduces to approximately half of the supply current when the logic input levels are at 0 to 5V.Power SuppliesThe MAX4533 operates with bipolar supplies between ±4.5V and ±18V. The V+ and V- supplies need not be symmetrical, but their difference can not exceed the absolute maximum rating of +44V. The MAX4533 oper-ates from a single supply between +9V and +36V when V- is connected to GND.M A X 4533Quad, Rail-to-Rail, Fault-Protected,SPDT Analog Switch 10______________________________________________________________________________________Table 1.

The reset output asserts when the V CC voltage falls below the factory-set threshold, V TH . The reset output de-asserts after the reset timeout (t RP ) when V CC voltage rises above the reset threshold plus the hysteresis voltage, (V TH + V HYST ). The reset output is guaranteed to be at the correct logic voltage for VCC voltage down to 1.3V. See Figure 1 for details.Manual Reset Input (MR)Many systems require manual reset capability, allowing the operator, a test technician, or external logic circuitry to initiate a reset. The MAX16143/MAX16145/MAX16147/MAX16149 provide this capability by featuring an manual reset input (MR). When a manual reset is initiated, the reset output asserts and remain asserted as long as the manual reset input is in active state. Reset deasserts after reset timeout when the manual reset input is released. Figure 1 shows the behavior of the manual reset configured as active-low, with 50kΩ pull (MR ). See Selector Guide for available options.Depending on the application, the manual reset input is factory-programmable to have either an internal pullup resistor, pulldown resistor of 50kΩ (typ), or be left floating.The pullup resistor allows the manual reset input to be left unconnected if not used. An external pullup resistor is required if the manual reset input option chosen does not have an internal pullup resistor. The maximum input voltage on MR is 5.5V.An alternative is to use a normally open momentary switch connected from MR (active-low) to GND, or from MR (active-high) to a logic-high voltage to create a manual-reset function. If a Long Debounce version is used, external debounce circuitry is not required, but an external pullup or pulldown will be required if a version without an internal resistor is used. If the manual reset input is driven from long cables, or the IC is used in a noisy environment, connect a 0.1μF capacitor from MR /MR to GND in order to provide additional noise immunity.Negative-Going V CC Transients ProtectionThese supervisory circuits are relatively immune to short-duration, negative-going V CC transients (glitches). The Maximum Transient Duration vs. Reset Threshold Overdrive graph (in the Typical Operating Characteristics section) shows the typical transient pulse width and amplitude required to trigger a reset. The reset threshold overdrive specifies how far the pulse falls below the actual reset threshold, and the maximum transient duration specifies the width of the pulse as it crosses the reset threshold. If a pulse occurs in the region above the curve, a reset triggers. If a pulse occurs in the region below the curve, a reset does not trigger.Figure 1.

Its high degree of directivity makes the MKH 416 a superb microphone for film and television, including outside broadcast applications. The microphone operates on the proven RF principle and is desi-gned for 48 V phantom powering.The MKH 416 is a combination of a pressure gradient trans-ducer and an interference tube microphone. It has a super-car-dioid pick-up pattern at low and medium frequencies, whereasat higher frequencies there is a transition to a lobar characte-ristic. Due to its operating principle, the MKH 416 is relatively insensitive to wind and pop noise and can therefore often be used as a soloist and broadcast microphone, without the need for an additional wind- or popshield. However, for outdoor re-cordings the use of an additional windshield is recommended. The frequency response intentionally has a slightly rising characteristic at high frequencies. The microphone has a low proximity effect and therefore provides a well balanced sound even when used close to the sound source.Principle of the RF circuitIn contrast to the high impedance of the capsules in conventio-nal “DC biased” condenser microphones, the capsule of an RF condenser microphone has a low impedance. The high polari-zation voltages normally required in condenser microphones are not necessary in the RF condenser microphone. RF con-denser microphones use a comparatively low RF bias voltage of less than 10 V, generated by a built-in low-noise oscillator (8 M Hz). The RF principle ensures increased operational reli-ability, particularly for outdoor recordings under extreme cli-matic conditions.Features•Increased directivity due to interference tube principle •Very low inherent self-noise•High sensitivity•Transformerless and fully floating balanced output •Rugged, suitable for adverse climatic conditions•Matt black all-metal bodyCleaning and maintaining the MKH 416-P48U3CAUTIONDAMAGE TO THE PRODUCT DUE TO LIQUIDS!Liquids entering the product can short-circuit the electronics or damage the mechanics.

A foldback current limit on the output stage provides immediate protection against short circuits over the whole common-mode voltage range (see Typical Operating Characteristics ). In addition, a thermal shut-down circuit forces the driver outputs into a high-imped-ance state if the die temperature rises excessively.Propagation DelayFigures 15–18 show the typical propagation delays. Skew time is simply the difference between the low-to-high and high-to-low propagation delay. Small driver/receiver skew times help maintain a symmetrical mark-space ratio (50% duty cycle).The receiver skew time, |tPRLH - t PRHL |, is under 10ns 20ns for the MAX3483E/MAX3488E). The driver skew times are 8ns for the MAX3485E/MAX3490E/MAX3491E, 12ns for the MAX3486E, and typically under 50ns for the MAX3483E/MAX3488E.Line Length vs. Data RateThe RS-485/RS-422 standard covers line lengths up to 4000 feet. For line lengths greater than 4000 feet, see Figure 21 for an example of a line repeater.Figures 19 and 20 show the system differential voltage for parts driving 4000 feet of 26AWG twisted-pair wire at 125kHz into 120Ω loads.For faster data rate transmission, please consult the factory.±15kV ESD Protection As with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electrostatic discharges encountered during handling and assembly. The driver outputs and receiver inputs of the MAX3483E family of devices have extra protection against static electricity. Maxim’s engineers have developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, shutdown, and powered down. After an ESD event, Maxim’s E versions keep working without latchup or damage.ESD protection can be tested in various ways; the trans-mitter outputs and receiver inputs of this product family are characterized for protection to the following limits:1)±15kV using the Human Body Model 2)±8kV using the Contact-Discharge method specified in IEC 1000-4-23)±15kV using IEC 1000-4-2’s Air-Gap method.ESD Test Conditions ESD performance depends on a variety of conditions. Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body Model Figure 22a shows the Human Body Model and Figure 22b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the test device through a 1.5kΩ resistor.IEC 1000-4-2The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifi-cally refer to integrated circuits. The MAX3483E family of devices helps you design equipment that meets Level 4 (the highest level) of IEC 1000-4-2, without the need for additional ESD-protection components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak cur-rent in IEC 1000-4-2, because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD withstand voltage measured to IEC 1000-4-2 is generally lower than that measured using the Human Body Model. Figure 23a shows the IEC 1000-4-2 model, and Figure 23b shows the current waveform for the ±8kV IEC 1000-4-2, Level 4ESD contact-discharge test. test.Figure 21.

MAX4162/MAX4163/MAX4164
UCSP, Micropower, Single-Supply, 10V, Rail-to-Rail I/O Op Amps
General Description
The MAX4162/MAX4163/MAX4164 are single/dual/quad, micropower operational amplifiers that combine an exceptional bandwidth to power consumption ratio with true rail-to-rail inputs and outputs. They consume a mere 25µA quiescent current per amplifier, yet achieve 200kHz gain-bandwidth product and are unity-gain stable while driving any capacitive load. The MAX4162/ MAX4163/MAX4164 operate from either a single supply (2.5V to 10V) or dual supplies (±1.25V to ±5V), with an input common-mode voltage range that extends 250mV beyond either supply rail. These amplifiers use a proprietary architecture to achieve a very high input commonmode rejection ratio without the midswing nonlinearities present in other rail-to-rail op amps. This architecture also maintains high open-loop gain and output swing while driving substantial loads.
