General DescriptionThe MAX4238/MAX4239 are low-noise, low-drift, ultra-high precision amplifiers that offer near-zero DC offset and drift through the use of patented autocorrelating zeroing techniques. This method constantly measures and compensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise. Both devices feature Rail-to-Rail ®outputs, operate from a single 2.7V to 5.5V supply, and consume only 600µA.An active-low shutdown mode decreases supply cur-rent to 0.1µA.The MAX4238 is unity-gain stable with a gain-band-width product of 1MHz, while the decompensated MAX4239 is stable with A V ≥10V/V and a GBWP of 6.5MHz. The MAX4238/MAX4239 are available in 8-pin narrow SO and 6-pin SOT23 packages.ApplicationsThermocouples Strain Gauges Electronic Scales Medical Instrumentation Instrumentation AmplifiersFeatureso Ultra-Low, 0.1µV Offset Voltage2.0µV (max) at +25°C2.5µV (max) at -40°C to +85°C3.5µV (max) at -40°C to +125°C o Low 10nV/o C Drifto Specified over the -40o C to +125o C Automotive Temperature Range o Low Noise: 1.5µV P-P from DC to 10Hz o 150dB A VOL , 140dB PSRR, 140dB CMRR o High Gain-Bandwidth Product1MHz (MAX4238)6.5MHz (MAX4239)o 0.1µA Shutdown Mode o Rail-to-Rail Output (R L = 1k Ω)o Low 600µA Supply Current o Ground-Sensing Inputo Single 2.7V to 5.5V Supply Voltage Rangeo Available in a Space-Saving 6-Pin SOT23 PackageMAX4238/MAX4239Ultra-Low Offset/Drift, Low-Noise,Precision SOT23 Amplifiers________________________________________________________________Maxim Integrated Products1Typical Application Circuit19-2424; Rev 1; 12/02For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Pin Configurations appear at end of data sheet.Rail-to-Rail is a registered trademark of Nippon Motorola, Ltd.Ordering InformationM A X 4238/M A X 4239Ultra-Low Offset/Drift, Low-Noise, Precision SOT23 Amplifiers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(2.7V ≤V CC ≤5.5V, V CM = GND = 0V, V OUT = V CC /2, R L = 10k Ωconnected to V CC /2, SHDN = V CC , T A = +25°C ,Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

These characteristics are achieved through a patented autozeroing technique that samples and cancels the input offset and noise of the amplifier.The pseudorandom clock frequency varies from 10kHz to 15kHz, reducing intermodulation distortion present in chopper-stabilized amplifiers.Offset Error SourcesTo achieve very low offset, several sources of error common to autozero-type amplifiers need to be consid-ered. The first contributor is the settling of the samplingcapacitor. This type of error is independent of input-source impedance, or the size of the external gain-set-ting resistors. Maxim uses a patented design technique to avoid large changes in the voltage on the sampling capacitor to reduce settling time errors.The second error contributor, which is present in both autozero and chopper-type amplifiers, is the charge injection from the switches. The charge injection appears as current spikes at the input, and combined with the impedance seen at the amplifier ’s input, con-tributes to input offset voltage. Minimize this feedthrough by reducing the size of the gain-setting resistors and the input-source impedance. A capacitor in parallel with the feedback resistor reduces the amount of clock feedthrough to the output by limiting the closed-loop bandwidth of the device.The design of the MAX4238/MAX4239 minimizes the effects of settling and charge injection to allow specifi-cation of an input offset voltage of 0.1µV (typ) and less than 2.5µV over temperature (-40°C to +85°C).1/f Noise1/f noise, inherent in all semiconductor devices, is inversely proportional to frequency. 1/f noise increases 3dB/octave and dominates amplifier noise at lower fre-quencies. This noise appears as a constantly changing voltage in series with any signal being measured. The MAX4238/MAX4239 treat 1/f noise as a slow varying offset error, inherently canceling the 1/f noise.MAX4238/MAX4239Ultra-Low Offset/Drift, Low-Noise,Precision SOT23 Amplifiers_______________________________________________________________________________________7Typical Operating Characteristics (continued)(V CC = 5V, V CM = 0V, R L = 10k Ωconnected to V CC /2, SHDN = V CC , T A = +25°C, unless otherwise noted.)SHUTDOWN WAVEFORMMAX4238/39 toc20R L = 10k ΩC L = 100pF10µs/divOUT2V/div1V/divSHDNDC TO 10Hz NOISEMAX4238/39 toc19V CC = 2.5V V EE = -2.5V1s/divOUT 2µV/divM A X 4238/M A X 4239Output Overload RecoveryAutozeroing amplifiers typically require a substantial amount of time to recover from an output overload. This is due to the time it takes for the null amplifier to correct the main amplifier to a valid output. The MAX4238/MAX4239 require only 3.3ms to recover from an output overload (see El ectrical Characteristics and Typical Operating Characteristics ).ShutdownThe MAX4238/MAX4239 feature a low-power (0.1µA)shutdown mode. When SHDN is pulled low, the clock stops and the device output enters a high-impedance state. Connect SHDN to V CC for normal operation.Applications InformationMinimum and Maximum GainConfigurationsThe MAX4238 is a unity-gain stable amplifier with a gain-bandwidth product (GBWP) of 1MHz. The MAX4239 is decompensated for a GBWP of 6.5MHz and is stable with a gain of 10V/V. Unlike conventional operational ampli-fiers, the MAX4238/MAX4239 have a maximum gain specification. To maintain stability, set the gain of the MAX4238 between A V = 1000V/V to 1V/V, and set the gain of the MAX4239 between A V = 6700V/V and 10V/V.ADC Buffer AmplifierThe low offset, fast settling time, and 1/f noise cancella-tion of the MAX4238/MAX4239 make these devices ideal for ADC buffers. The MAX4238/MAX4239 are well suited for low-speed, high-accuracy applications such as strain gauges (see Typical Application Circuit ).Error Budget ExampleWhen using the MAX4238/MAX4239 as an ADC buffer,the temperature drift should be taken into account when determining the maximum input signal. With a typical off-set drift of 10nV/°C, the drift over a 10°C range is 100nV.Setting this equal to 1/2LSB in a 16-bit system yields a full-scale range of 13mV. With a single 2.7V supply, an acceptable closed-loop gain is A V = 200. This provides sufficient gain while maintaining headroom.Chip InformationTRANSISTOR COUNT: 821PROCESS: BiCMOSUltra-Low Offset/Drift, Low-Noise, Precision SOT23 Amplifiers 8_______________________________________________________________________________________MAX4238/MAX4239Ultra-Low Offset/Drift, Low-Noise,Precision SOT23 Amplifiers_______________________________________________________________________________________9Package Information(The package drawing(s) in this data sheet may not reflect the most current specifications.

General DescriptionThe MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/MAX6348 microprocessor (µP) supervisory circuits moni-tor the power supplies in µP and digital systems. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 2.5V, 3V, 3.3V, and 5V powered circuits.These circuits perform a single function: they assert a reset signal whenever the V CC supply voltage declines below a preset threshold, keeping it asserted for at least 100ms after V CC has risen above the reset threshold.The only difference between the devices is their output.The MAX6326/MAX6346 (push-pull) and MAX6328/MAX6348 (open-drain) have an active-low reset output.The MAX6327/MAX6347 have an active-high push-pull reset output. All of these parts are guaranteed to be in the correct state for V CC down to 1V. The reset compara-tor is designed to ignore fast transients on V CC . Reset thresholds are factory-trimmable between 2.2V and 4.63V, in approximately 100mV increments. Twenty-one standard versions are available. Contact the factory for availability of nonstandard versions.Ultra-low supply currents (1µA max for the MAX6326/MAX6327/MAX6328) make these parts ideal for use in portable equipment.

Connecting the µP supervisor’s RESET output directly to the microcon-troller’s (µC’s) RESET pin with a single pull-up resistor allows either device to assert reset (Figure 1).Negative-Going V CC TransientsIn addition to issuing a reset to the µP during power-up,power-down, and brownout conditions, these devices are relatively immune to short-duration, negative-going V CC transients (glitches).The Typical O perating Characteristics show the Maxi-mum Transient Duration vs. Reset Threshold Overdrive graph, for which reset pulses are not generated. The graph shows the maximum pulse width that a negative-going V CC transient may typically have when issuing a reset signal. As the amplitude of the transient increas-es, the maximum allowable pulse width decreases.Figure 1. Interfacing to µPs with Bidirectional Reset PinsTable 1.

RUDAT-6000-30Key FeaturesProgrammable AttenuatorUSB / RS232Case Style: MS1813Software PackageThe Big Deal• Attenuation range, 30 dB• Fine attenuation resolution, 0.25 dB• Short attenuation transition time (650 ns)• Compact size, 2.0 x 3.0 x 0.6”• USB and RS232 control50Ω 0 – 30 dB, 0.25 dB step 1 to 6000 MHzProduct OverviewMini-Circuits’ RUDAT-6000-30 is a general purpose, single channel programmable attenuator suitable for a wide range of signal level control applications from 1 MHz to 6 GHz. The Attenuator provides 0 to 30 dB attenuation in 0.25 dB steps. Its unique design maintains linear attenuation change per dB, even at the highest attenuation settings.The attenuator is housed in a compact and rugged package with SMA female connectors on the bi-directional input and output RF ports, a standard 9 pin D-Sub and a USB type Mini-B power and control ports.The attenuator can be controlled via USB or RS232 (via D-Sub connector). Full software support is provided and can be downloaded from our website any time at /softwaredownload/patt.html . The package includes our user-friendly GUI application for Windows ® and a full API with programming instructions for Windows ® and Linux ® environments (both 32-bit and 64-bit systems).Trademarks: Windows is a registered trademark of Microsoft Corporation in the United States and other countries.

USB cable11 Attenuator RF ports are interchangeable, and support simultaneous, bidirectional signal transmission, however the specifications are guaranteed forthe RF in and RF out as noted on the label. There may be minor changes in performance when injecting signals to the RF Out port. 2 Max accuracy defined as ±[absolute error+% of attenuation setting] for example when setting the attenuator to 18 dB attenuation the maximum error will be: ±(0.95+0.02x18)= ±(0.95+0.36)= ± 1.31 dB.3 Total operating input power from both RF In and RF Out out ports. Compression level not noted as it exceeds max safe operating power level.4 Isolation is defined as max attenuation plus insertion loss; this is the path loss through the attenuator when initially powered up. After a brief delay (~0.5 sec typically) the attenuator will revert to a user defined “power-up” state (either max attenuation or a pre-set value).5 Tested with 1 MHz span between signals.6 Minimum Dwell Time is the time the RUDAT will take to respond to a command to change attenuation states without communication delays. In PC control add communication delays (on the order of msec for USB) to get actual response time.7Attenuation Transition Time is specified as the time between starting to change the attenuation state and settling on the requested attenuation state.8 Supply voltage +5V at Pin#1 of D-sub connector applies to units with S/N 11405010010 and greater.9 Power on sequence for RS232 control: Connect 5V power followed by the control lines.Absolute Maximum RatingsPermanent damage may occur if any of these limits are exceeded. Operation in the range between the max operating power and the absolute maximum rating for extended periods of time may result in reduced life and reliability.Operating Temperature 0°C to 50°C Storage Temperature-20°C to 85°C Voltage input at RS232 receive pin -30V to +30V Voltage input at RS232 transmit pin 0V to +4V Voltage input at RS232 Pin#1-1V to +6VV USB Max.6V DC voltage at RF port16V Total RF power for RF In & RF Out @ 1 to 10 MHz +13 dBm @ 10 to 6000 MHz+23 dBm10 Block diagram and connection shown apply to units with S/N 11405010010 and greater, for units with lowerS/N see archive section on page 9.11 Pin#1 can be used as supply voltage (+) pin instead of USB connection.

MEMORY存储芯片MAX823TEUK+T中文规格书
Manual Reset Input Many μP-based products require manual reset capabil -ity, allowing the operator, a test technician, or external logic circuitry to initiate a reset. A logic low on MR asserts reset. Reset remains asserted while MR is low, and for the Reset Active Timeout Period (t RP ) after MR returns high. This input has an internal 20kΩ pull-up resistor, so it can be left open if it is not used. MR can be driven with TTL or CMOS-logic levels, or with open-drain/collector outputs. Connect a normally open momentary switch from MR to GND to create a manual-reset function; external debounce circuitry is not required. If MR is driven from long cables or if the device is used in a noisy environment, connecting a 0.1μF capacitor from MR to ground provides additional noise immunity.Reset Threshold Accuracy The MAX811/MAX812 are ideal for systems using a 5V ±5% or 3V ±5% power supply with ICs specified for 5V ±10% or 3V ±10%, respectively. They are designed to meet worst-case specifications over temperature. The reset is guaranteed to assert after the power supplyfalls out of regulation, but before power drops below theminimum specified operating voltage range for the systemICs. The thresholds are pre-trimmed and exhibit tight dis -tribution, reducing the range over which an undesirable reset may occur.PINNAME FUNCTION MAX811MAX81211GND Ground 2—RESET Active-Low Reset Output. RESET remains low while V CC is below the reset threshold or while MR is held low. RESET remains low for the Reset Active Timeout Period (t RP ) after the reset conditions are terminated.—2RESET Active-High Reset Output. RESET remains high while V CC is below the reset threshold or while MR is held low. RESET remains high for Reset Active Timeout Period (t RP ) after the reset conditions are terminated.33MR Manual Reset Input. A logic low on MR asserts reset. Reset remains asserted as long as MR is low and for 180ms after MR returns high. This active-low input has an internal 20kΩ pull-up resistor. It can be driven from a TTL or CMOS-logic line, or shorted to ground with a switch. Leave open if unused.44V CC +5V, +3.3V, or +3V Supply Voltage Detailed DescriptionReset OutputA microprocessor’s (μP’s) reset input starts the μP in aknown state. These μP supervisory circuits assert resetto prevent code execution errors during power-up, power-down, or brownout conditions.RESET is guaranteed to be a logic low for V CC > 1V.Once V CC exceeds the reset threshold, an internal timerkeeps RESET low for the reset timeout period; after thisinterval, RESET goes high.If a brownout condition occurs (V CC dips below the resetthreshold), RESET goes low. Any time V CC goes belowthe reset threshold, the internal timer resets to zero, andRESET goes low. The internal timer starts after V CC returns above the reset threshold, and RESET remainslow for the reset timeout period.The manual reset input (MR ) can also initiate a reset. See the Manual Reset Input section.The MAX812 has an active-high RESET output that is theinverse of the MAX811’s RESET output.MAX811/MAX8124-Pin μP Voltage Monitorswith Manual Reset InputPin DescriptionTerminal Voltage (with respect to GND)V CC.....................................................................-0.3V to 6.0V All Other Inputs .....................................-0.3V to (V CC + 0.3V) Input Current, V CC, MR......................................................20mA Output Current, RESET or RESET ....................................20mA Continuous Power Dissipation (T A = +70°C)SOT143 (derate 4mW/°C above +70°C) .....................320mW Operating Temperature Range ...........................-40°C to +85°C Junction Temperature ......................................................+150°C Storage Temperature Range ............................-65°C to +160°C Lead Temperature (soldering, 10sec) .............................+300°C(V CC = 5V for L/M versions, V CC = 3.3V for T/S versions, V CC = 3V for R version, T A = -40°C to +85°C, unless otherwise noted.

MAX306中文资料
_______________General DescriptionThe MAX306/MAX307 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less than 100Ω), which is matched to within 5Ωbetween channels and remains flat over the specified analog signal range (7Ωmax). They also offer low leak-age over temperature (I NO(OFF)less than 2.5nA at +85°C) and fast switching speeds (t TRANS less than 250ns). The MAX306 is a single-ended 1-of-16 device,and the MAX307 is a differential 2-of-8 device.The MAX306/MAX307 are fabricated with Maxim’s improved 44V silicon-gate process. Design improve-ments yield extremely low charge injection (less than 10pC) and guarantee electrostatic discharge (ESD)protection greater than 2000V.These muxes operate with a single +4.5V to +30V sup-ply, or bipolar ±4.5V to ±20V supplies, while retaining TTL/CMOS-logic input compatibility and fast switching.CMOS inputs provide reduced input loading. These improved parts are plug-in upgrades for the industry-standard DG406, DG407, DG506A, and DG507A.________________________ApplicationsSample-and-Hold Circuits Test Equipment Heads-Up DisplaysGuidance and Control Systems Military RadiosCommunications Systems Battery-Operated Systems PBX, PABXAudio Signal Routing____________________________Featureso Guaranteed On-Resistance Match Between Channels, <5ΩMaxo Low On-Resistance, <100ΩMaxo Guaranteed Flat On-Resistance over Specified Signal Range, 7ΩMaxo Guaranteed Charge Injection, <10pC o I NO(OFF)Leakage <2.5nA at +85°C o I COM(OFF)Leakage <20nA at +85°C o ESD Protection >2000Vo Plug-In Upgrade for Industry-Standard DG406/DG407/DG506A/DG507Ao Single-Supply Operation (+4.5V to +30V)Bipolar-Supply Operation (±4.5V to ±20V)o Low Power Consumption, <1.25mW o Rail-to-Rail Signal Handling o TTL/CMOS-Logic CompatibleMAX306/MAX307Precision, 16-Channel/Dual 8-Channel,High-Performance, CMOS Analog Multiplexers________________________________________________________________Maxim Integrated Products 1_____________________Pin Configurations/Functional Diagrams/Truth TablesCall toll free 1-800-998-8800 for free samples or literature.19-0270; Rev 0; 8/94Ordering Information continued at end of data sheet.* Contact factory for dice specifications.M A X 306/M A X 307Precision, 16-Channel/Dual 8-Channel,High-Performance, CMOS Analog Multiplexers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS—Dual Supplies(V+ = +15V, V- = -15V, GND = 0V, V AH = +2.4V, V AL = +0.8V, T A = T MIN to T MAX , unless otherwise noted.)Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The MAX306/MAX307 switches operate with ±4.5V to ±20V bipolar supplies or with a +4.5V to +30V single supply; connect V- to GND when operating with a single supply. Also, both device types can operate with unbalanced supplies such as +24V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.)Overvoltage ProtectionProper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maxi-mum ratings because stresses beyond the listed rat-ings may cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by either the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage pro-tection (Figure 1). Adding diodes reduces the analogsignal range to 1V above V+ and 1V below V-, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference between V+ and V- should not exceed +44V.M A X 306/M A X 307Precision, 16-Channel/Dual 8-Channel,High-Performance, CMOS Analog Multiplexers 6_______________________________________________________________________________________Output–bidirectionalCOM28Address Inputs A3–A014–17Enable InputsEN 18Analog Inputs–bidirectional NO1–NO819–26Negative Supply Voltage Input V-27Ground GND 12Analog Inputs–bidirectional NO16–NO94–11MAX306PINNo Internal Connections N.C.2, 3, 13Positive Supply Voltage Input V+1FUNCTIONNAME_____________________________________________________________Pin DescriptionsDiodesMAX306/MAX307Precision, 16-Channel/Dual 8-Channel,High-Performance, CMOS Analog Multiplexers_______________________________________________________________________________________7______________________________________________Test Circuits/Timing DiagramsM A X 306/M A X 307Precision, 16-Channel/Dual 8-Channel,High-Performance, CMOS Analog Multiplexers 8________________________________________________________________________________________________________________________Test Circuits/Timing Diagrams (continued)Figure 5.

MAX4823ETP-T中文资料
General DescriptionThe MAX4822–MAX4825 8-channel relay drivers offer built-in kickback protection and drive +3V/+5V non-latching or dual-coil-latching relays. Each independent open-drain output features a 2.7Ω(typ) on-resistance and is guaranteed to sink 70mA (min) of load current.These devices consume less than 300µA (max) quies-cent current and have 1µA output off-leakage current.A Zener-kickback-protection circuit significantly reduces recovery time in applications where switching speed is critical.The MAX4822/MAX4824 feature a unique power-save mode where the relay current, after activation, can be reduced to a level just above the relay hold-current threshold. This mode keeps the relay activated while significantly reducing the power consumption.The MAX4822/MAX4823 feature a 10MH z SPI™-/QSPI™-/MICROWIRE™-compatible serial interface.Input data is shifted into a shift register and latched to the outputs when CS transitions from low to high. Each data bit in the shift register corresponds to a specific output, allowing independent control of all outputs. The MAX4824/MAX4825 feature a 4-bit parallel-input interface. The first 3 bits (A0, A1, A2) determine the out-put address, and the fourth bit (LVL) determines whether the selected output is switched on or off. Data is latched to the outputs when CS transitions from low to high.The MAX4822–MAX4825 feature separate set and reset functions, allowing turn-on or turn-off of all outputs simultaneously with a single control line. Built-in hys-teresis (Schmidt trigger) on all digital inputs allows these devices to be used with slow-rising and falling signals, such as those from optocouplers or RC power-up initialization circuits. The MAX4822–MAX4825 are available in space-saving 4mm x 4mm, 20-pin thin QFN packages. They are specified over the -40°C to +85°C extended temperature range.ApplicationsATE EquipmentDSL Redundancy Protection (ADSL/VDSL/HDSL)T1/E1 Redundancy Protection T3/E3 Redundancy Protection Industrial EquipmentTest Equipment (Oscilloscopes, Spectrum Analyzers)Features♦Built-In Zener Kickback Protection for Fast Recovery ♦Programmable Power-Save Mode Reduces Relay Power Consumption (MAX4822/MAX4824)♦10MHz SPI-/QSPI-/MICROWIRE-Compatible Serial Interface ♦Eight Independent Output Channels ♦Drive +3V and +5V Relays♦Guaranteed 70mA (min) Coil Drive Current ♦Guaranteed 5Ω(max) R ON♦SET / RESET Functions to Turn On/Off All Outputs Simultaneously ♦Serial Digital Output for Daisy Chaining ♦Optional Parallel Interface (MAX4824/MAX4825)♦Low 300µA (max) Quiescent Supply Current ♦Space-Saving, 4mm x 4mm, 20-Pin TQFN PackageMAX4822–MAX4825+3.3V/+5V , 8-Channel Relay Drivers with FastRecovery Time and Power-Save Mode________________________________________________________________Maxim Integrated Products1Ordering Information19-3789; Rev 0; 8/05For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .*For maximum heat dissipation, packages have an exposed pad (EP) on the bottom.

The MAX4823 does not support power-save mode, so the serial interface con-sists of an 8-bit-only shift register for faster control.The MAX4822 consists of a 16-bit shift register and par-allel latch controlled by SCLK and CS . The input to the shift register is a 16-bit word. In the MAX4822, the first 8 bits determine the register address and are followedsponds to the MSB of the 8-bit register address in Figure 1, while bit D7 corresponds to the MSB of the 8bits of data in the same Figure 1.The MAX4823 consists of an 8-bit shift register and par-allel latch controlled by SCLK and CS . The input to the shift register is an 8-bit word. Each data bit controls one of the eight outputs, with the most significant bit (D7) corresponding to OUT8, and the least significant bit (D0) corresponding to OUT1 (see Figure 2).MAX4822–MAX4825+3.3V/+5V , 8-Channel Relay Drivers with FastRecovery Time and Power-Save Mode_______________________________________________________________________________________9M A X 4822–M A X 4825When CS is low (MAX4822/MAX4823 device is select-ed), data at DIN is clocked into the shift register syn-chronously with SCLK’s rising edge. Driving CS from low to high latches the data in the shift register (Figures 5 and 6).DOUT is the output of the shift register. Data appears on DOUT synchronously with SCLK’s falling edge and is identical to the data at DIN delayed by eight clock cycles for the MAX4823, or 16 clock cycles for the MAX4822. When shifting the input data, A7 is the first input bit in and out of the shift register for the MAX4822device. D7 is the first bit in or out of the shift register for+3.3V/+5V , 8-Channel Relay Drivers with Fast Recovery Time and Power-Save Mode 10______________________________________________________________________________________Figure 1. 16-Bit Register Map for MAX4822the MAX4823 device. If the address A0…….A7 is not 00h or 01h, then the outputs and the PSAVE configura-tion register are not updated. The address is stored in the shift register only.While CS is low, the OUT_ outputs always remain in their previous state. For the MAX4823, drive CS high after 8bits of data have been shifted in to update the output state of the MAX4823, and to further inhibit data from entering the shift register. For the MAX4822, drive CS high after 16 bits of data have been shifted in to update the output state of the MAX4822, and to further inhibit data from entering the shift register. When CS is high, transi-tions at DIN and SCLK have no effect on the output, and the first input bit A7 (or D7) is present at DOUT.For the MAX4822, if the number of data bits entered while CS is low is greater or less than 16, the shift regis-ter contains only the last 16 bits, regardless of when they were entered. For the MAX4823, if the number of data bits entered while CS is low is greater or less than 8, the shift register contains only the last 8 data bits,regardless of when they were entered.Parallel Interface (MAX4824/MAX4825)The parallel interface consists of 3 address bits (A0,A1, A2) and one level selector bit (LVL). The address bits determine which output is updated, and the level bit determines whether the addressed output is switched on (LVL = high) or off (LVL = low). When CS is high, the address and level bits have no effect on the state of the outputs.

Address data entered after CS is pulled low is not reflected in the state of the outputs following the next low-to-high transition on CS (Figure 7).SET/RESET FunctionsThe MAX4822–MAX4825 feature set and reset inputs that allow simultaneous turn-on or turn-off of all outputs using a single control line. Drive SET low to set all latch-es and registers to 1 and turn all outputs on. SET over-rides all serial/parallel control inputs. Drive RESET low to clear all latches and registers and to turn all outputs off. RESET overrides all other inputs including SET .Power-On ResetThe MAX4822–MAX4825 feature power-on reset. The power-on reset function causes all latches to be cleared automatically upon power-up. This ensures that all outputs come up in the off or high-impedance state.Applications InformationDaisy ChainingThe MAX4822/MAX4823 feature a digital output (DOUT) that provides a simple way to daisy chain multi-ple devices. This feature allows driving large banks of relays using only a single serial interface. To daisy chain multiple devices, connect all CS inputs together,and connect the DOUT of one device to the DIN of another device (see Figure 8). During operation, a stream of serial data is shifted through the MAX4822/MAX4823 devices in series. When CS goes high, all outputs update simultaneously.The MAX4822/MAX4823 can also be used in a slave configuration that allows individual addressing of devices. Connect all the DIN inputs together, and usethe CS input to address one device at a time. Drive CS low to select a slave and input the data into the shift register. Drive CS high to latch the data and turn on the appropriate outputs. Typically, in this configuration only one slave is addressed at a time.Power-Save ModeThe MAX4822/MAX4824 feature a unique power-save mode where the relay current, after activation, can be reduced to a level just above the relay hold-current threshold. This mode keeps the relay activated while significantly reducing the power consumption.In serial mode (MAX4822), choose between seven cur-rent levels ranging from 30% to 90% of the nominal cur-rent in 10% increments. The actual percentage is determined by the power-save configuration register (Figure 1).In parallel mode (MAX4824), the power-save current is fixed at 60% of the nominal current.Power-Save TimerEvery time there is a write operation to the device (CS transitions from low to high), the MAX4822/MAX4824start charging the capacitor connected to PSAVE. The serial power-save implementation is such that a write operation does not change the state of channels already in power-save mode (unless the write turns the channel OFF).After a certain time period, t PS (determined by the capacitor value), the capacitor reaches a voltage threshold that sets all active outputs to power-save mode. The t PS period should be made long enough to allow the relay to turn on completely. The time period t PS can be adjusted by using different capacitor valuesRecovery Time and Power-Save Mode 12______________________________________________________________________________________Figure 5. 3-Wire Serial-Interface Operation for MAX4822connected to PSAVE. The value t PS is given by the fol-lowing formula:t PS = 32 x Cwhere C is in µF and t PS is in ms.For example, if the desired t PS is 20ms, then the required capacitor value is 20 / 32 = 0.625µF.Power-Save Mode AccuracyThe current through the relay is controlled by setting the voltage at OUT_ to a percentage of the V CC supply as specified under the Electrical Characteristics and in the register description. The current through the relay (I OUT )depends on the switch on-resistance, R ON,in addition to the relay resistance R R according to the fol-lowing relation:I OUT = V CC / (R ON + R R )The power-save, current-setting I PS depends on the fraction αof the supply voltage V CC that is set by the loop depending on the following relation:I PS = V CC - (αx V CC ) / R RTherefore:I PS / I OUT = (1- α) x (1 + R ON / R R )This relation shows how the fraction of reduction in the current depends on the switch on-resistance, as well as from the accuracy of the voltage setting (α). The higher the R ON with respect to R R, the higher the inaccuracy.This is particularly true at low voltage when the relay resistance is low (less than 40Ω) and the switch can account for up to 10% of the total resistance. In addi-tion, when the supply-voltage setting (α) is low (10% or 20%) and the supply voltage (V CC ) is low, the voltage drop across the switch (I OUT x R ON ) may already exceed, or may be very close to, the desired voltage-setting value.Daisy Chaining and Power-Save ModeIn a normal configuration using the power-save feature,several MAX4822s can be daisy chained as shown in Figure 9. For each MAX4822, the power-save timing t PD (time it takes to reduce the relay current once the relay is actuated) is controlled by the capacitor con-nected to PSAVE.An alternative configuration that eliminates the PSAVE capacitors uses a common PSAVE control line driven by an open-drain n-channel MOSFET (Figure 10). In this con-figuration, the PSAVE inputs are connected together to asynchronously control the power-save timing for all the MAX4822s in the chain. The µC/µP drives the n-channel MOSFET low for the duration of a write cycle to the SPI chain, plus some delay time to allow the relays to close.(This time is typically specified in the relay data sheet.)Once this delay time has elapsed, the n-channel MOSFET is turned off, allowing the MAX4822’s internal 35µA pullup current to raise PSAVE to a logic-high level, activating the power-save mode in all active outputs.MOSFET SelectionIn the daisy-chain configuration of Figure 10, the n-channel MOSFET drives PSAVE low. When the n-channel MOSFET is turned off, PSAVE is pulled high by an internal 35µA pullup in each MAX4822, and the power-save mode is enabled. Because of the paralleled PSAVE pullup currents, the required size of the n-channel MOSFET depends upon the number of MAX4822 devices in the chain. Determine the size of the n-channel MOSFET by the following relation:R ON < 1428 / NMAX4822–MAX4825Recovery Time and Power-Save Mode______________________________________________________________________________________13Figure 6. 3-Wire Serial-Interface Operation for the MAX4823Figure 7. Parallel-Interface Timing DiagramM A X 4822–M A X 4825where N is the total number of MAX4822 devices in a single chain, and R ON is the on-resistance of the n-channel MOSFET in Ωs.For example, if N = 10:R ON < 142ΩAn n-channel MOSFET with R ON less than 142Ωis required for a daisy chain of 10 MAX4822 devices.Inductive Kickback Protection withFast Recovery TimeThe MAX4822–MAX4825 feature built-in inductive kick-back protection to reduce the voltage spike on OUT_generated by a relay’s coil inductance when the output is suddenly switched off. An internal Zener clamp allows the inductor current to flow back to ground. The Zener configuration significantly reduces the recovery time (time it takes to turn off the relay) when compared to protection configurations with just one diode across the coil.Recovery Time and Power-Save Mode 14______________________________________________________________________________________Figure 9.

5T828 PCB InformationThis section provides parts lists, a grid reference index, PCB layouts and circuit diagrams for the T828 power amplifier.This section contains the following information.Section Title IPN Page 5.1Introduction 5.1.3 5.2T828 PA PCB220-01197-02 5.2.15.1IntroductionPCB IdentificationAll PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, which is screen printed onto the PCB (usually on the top side). The last 2 digits of this number define the issue status, which starts at 00 and increments through 01, 02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are therefore not included in this manual. A let-ter following the 10 digit IPN has no relevance in identifying the PCB for service purposes.Note:It is important that you identify which issue PCB you are working on so that you canrefer to the appropriate set of PCB information.Parts ListsThe 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). Your spare parts orders can be handled more efficiently if you quote the IPN and provide a brief descrip-tion of the part.The components listed in this parts list are divided into two main types: those with a circuit refer-ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).Those with a circuit reference are grouped in alphabetical order and then in numerical order within each group. Each component entry comprises three or four columns, as shown below:The miscellaneous and mechanical section lists the variant and common parts in IPN order.Variant ComponentsA variant component is one that has the same circuit reference but different value or specification in different product types. Variant components are indicated by a character prefix such as “&”, “#” or “=”.circuit reference -lists components in alphanumeric ordervariant column -indicates that this is a variant component which is fitted only to the product type listed Internal Part Number -order the component by this numberdescription -gives a brief description of the componentGrid Reference IndexTo assist in locating components and labelled pads on the PCB layouts and circuit diagrams, a com-ponent grid reference index has been provided. This index lists the components and pads in alpha-numeric order, along with the appropriate alphanumeric grid references, as shown below:Using CAD Circuit DiagramsReading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric border. The circuit diagrams in this manual use letters to represent the horizontal axis, and num-bers for the vertical axis. These circuit diagram “grid references” are useful in following a circuit that is spread over two or more sheets.When a line representing part of the circuitry is discontinued, a reference will be given at the end of the line to indicate where the rest of the circuitry is located. The first digit refers to the sheet number and the last two characters refer to the location on that sheet of the continuation of the circuit (e.g.1-D4).If more than one line is represented (indicated by a double thickness line), a dot with a reference label will follow the route each individual line represents.circuit diagram reference PCB layout referencecomponents listed in alphanumeric orderlayer number -1 = top side layer 2 = bottom side layercomponent location on the layersheet numbercomponent location on the sheet。
KT6328A蓝牙芯片低功耗版本的详细说明
一、简介鉴于之前，客户一直反馈我们的KT6368A的蓝牙芯片低功耗还是偏高。
所以我们特地优化了一个低功耗的版本。
这里命名为KT6328A。
此版优化的地方在两点：1、去掉了SPP功能。
只保留了BLE低功耗的功能2、上电默认就是低功耗模式。
上电默认前5秒是正常收发指令，5秒之后进入低功耗。
不接收AT指令。
==》这样做的目的是方便客户可以AT指令设置参数。
因为进入低功耗之后，芯片所有的外设必须关闭。
==》当然对于很多需要频繁上电和锻炼的产品，也可以联系我们修改一下固件【批量才配合修改】，改成上电直接低功耗，因为默认版本的固件，也是为了方便客户测试，才这样设计的，没办法3、ble连接成功之后，就会开启uart外设，可以正常接收串口AT指令，以及透传功能4、不在意5mA平均功耗的产品，推荐使用KT6368A的双模版本，更加的稳定成熟和好用二、详细说明2.1低功耗的一些参数--低功耗版本KT6328A1、注意此功耗，是芯片上电默认就是此模式。
注意购买，一定要购买KT6328A这个版本。
其他版本不行这个版本，也可以通过蓝牙名来识别“KT6328A-BLE-2.0”2、芯片默认出厂，开机前5秒是正常模式，5秒之后就进入低功耗。
方便客户测试序号电流说明开机瞬间15mA1、芯片开机需要初始化很多外设。
所以瞬间电流比较大达到15mA2、但是这个时间仅仅维持200ms，就进入低功耗状态了工作状态-未连接30uA5mA交替1、芯片正常工作状态，正常对外广播，处于一个睡眠、唤醒广播、睡眠这样的周期性状态。
其实目的是为了节省功耗2、周期是500ms。
100ms广播一次，400ms就睡眠3、广播一次电流就是4mA然后进入睡眠，就变成30uA工作状态-已连接 4.3mA当连接成功之后，芯片就不再进入睡眠。
而是一次处于工作状态了2.2注意事项AT+VER2.0-20211111TM+KT6328A-BLE-2.1---手机端会搜索到这个名字TN+3031E54D77D9T4+01T5+00QL+01--进入低功耗模式2.2相对高精度的电流测试曲线1、可以看到开机瞬间的电流在5mA，随后降到4mA等待几秒之后，就进入低功耗广播状态了2、低功耗的广播状态，平均电流是185.4uA3、最低的时候，是20uA。

General DescriptionThe MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/MAX6348 microprocessor (µP) supervisory circuits moni-tor the power supplies in µP and digital systems. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 2.5V, 3V, 3.3V, and 5V powered circuits.These circuits perform a single function: they assert a reset signal whenever the V CC supply voltage declines below a preset threshold, keeping it asserted for at least 100ms after V CC has risen above the reset threshold.The only difference between the devices is their output.The MAX6326/MAX6346 (push-pull) and MAX6328/MAX6348 (open-drain) have an active-low reset output.The MAX6327/MAX6347 have an active-high push-pull reset output. All of these parts are guaranteed to be in the correct state for V CC down to 1V. The reset compara-tor is designed to ignore fast transients on V CC . Reset thresholds are factory-trimmable between 2.2V and 4.63V, in approximately 100mV increments. Twenty-one standard versions are available. Contact the factory for availability of nonstandard versions.Ultra-low supply currents (1µA max for the MAX6326/MAX6327/MAX6328) make these parts ideal for use in portable equipment.

Connecting the µP supervisor’s RESET output directly to the microcon-troller’s (µC’s) RESET pin with a single pull-up resistor allows either device to assert reset (Figure 1).Negative-Going V CC TransientsIn addition to issuing a reset to the µP during power-up,power-down, and brownout conditions, these devices are relatively immune to short-duration, negative-going V CC transients (glitches).The Typical O perating Characteristics show the Maxi-mum Transient Duration vs. Reset Threshold Overdrive graph, for which reset pulses are not generated. The graph shows the maximum pulse width that a negative-going V CC transient may typically have when issuing a reset signal. As the amplitude of the transient increas-es, the maximum allowable pulse width decreases.Figure 1. Interfacing to µPs with Bidirectional Reset PinsTable 1.
