      AD5227BUJZ50-R2
      GENERAL DESCRIPTIONThe AD5227 is Analog Devices’ latest 64-step up/down control digital potentiometer1. This device performs the same electronic adjustment function as a 5 V potentiometer or variable resistor. Its simple 3-wire up/down interface allows manual switching or high speed digital control.FEATURES64-position digital potentiometer10 kΩ, 50 kΩ, 100 kΩ end-to-end terminal resistanceSimple up/down digital or manual configurable controlMidscale presetLow potentiometer mode tempco = 10 ppm/°CLow rheostat mode tempco = 35 ppm/°CUltralow power, IDD = 0.4 μA typ and 3 μA maxFast adjustment time, ts = 1 μsChip select enable multiple device operationLow operating voltage, 2.7 V to 5.5 VAutomotive temperature range, −40°C to +105°CCompact thin SOT-23-8 (2.9 mm × 3 mm) Pb-free packageAPPLICATIONSMechanical potentiometer and trimmer replacementsLCD backlight, contrast, and brightness controlsPortable electronics level adjustmentProgrammable power supplyDigital trimmer replacementsAutomatic closed-loop control

      AD5171BRJZ10-R7
      GENERAL DESCRIPTIONThe AD5171 is a 64-position, one-time programmable (OTP) digital potentiometer 2 that uses fuse link technology to achieve the memory retention of the resistance setting function. OTP is a cost-effective alternative over the EEMEM approach for users who do not need to reprogram new memory settings in the digital potentiometer. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors.FEATURES64 positionOne-time programmable (OTP) set-and-forget resistance setting—low cost alternative over EEMEMUnlimited adjustments prior to OTP activation5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ end-to-end resistanceLow temperature coefficient: 5 ppm/°C in potentiometer modeLow temperature coefficient: 35 ppm/°C in rheostat modeCompact standard 8-lead SOT-23 packageLow power: IDD = 10 μA maximumFast settling time: tS = 5 μs typical in power-upI2C-compatible digital interfaceComputer software replaces microcontroller in factory programming applicationsFull read/write of wiper registerExtra I2C device address pinLow operating voltage: 2.7 V to 5.5 VOTP validation check functionAutomotive temperature range: −40°C to +125°CAPPLICATIONSSystem calibrationsElectronics level settingsMechanical trimmers and potentiometer replacementsAutomotive electronics adjustmentsGain control and offset adjustmentsTransducer circuit adjustmentsProgrammable filters up to 1.5 MHz BW 1

      AD5273BRJZ1-REEL7
      GENERAL DESCRIPTIONThe AD5273 is a 64-position, one-time programmable (OTP) digital potentiometer4 that employs fuse link technology to achieve permanent program setting. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors. It allows unlimited adjustments before permanently setting the resistance values. The AD5273 is programmed using a 2-wire, I2C-compatible digital control. During write mode, a fuse blow command is executed after the final value is determined, thereby freezing the wiper position at a given setting (analogous to placing epoxy on a mechanical trimmer).FEATURES64 positionsOne-time programmable (OTP)1 set-and-forgetResistance setting—low cost alternative over EEMEMUnlimited adjustments prior to OTP activation1 kΩ, 10 kΩ, 50 kΩ, 100 kΩ end-to-end terminal resistanceCompact 8-lead SOT-23 standard packageUltralow power: IDD = 5 µA maximumFast settling time: tS = 5 µs typical during power-upI2C-compatible digital interfaceComputer software2 replaces microcontroller infactory programming applicationsWide temperature range: −40°C to +105°CLow operating voltage: 2.7 V to 5.5 VOTP validation check functionAPPLICATIONSSystem calibrationsElectronics level settingsMechanical potentiometers and trimmer replacementTransducer circuit adjustmentsProgrammable filters up to 6 MHz BW3
