AD5231BRUZ10-REEL7 is a 1024-tap non-volatile digital potentiometer (10kΩ) from ADI with 2-wire I2C interface in SOT23-8 package, integrated EEPROM to store tap resistance after power loss, industrial temp -40~+85℃. Drop-in replacement for mechanical trim pots for analog gain trimming, reference voltage calibration and sensor offset compensation.

1. Total Resistance Value: 10 kΩ 2. Tap Count: 1024 adjustable resistance steps 3. Memory: On-chip EEPROM retains tap position through power cycles 4. Communication: 2-wire I2C bus up to 400kHz 5. Package: SOT-23-8 6. Operating Temp: -40℃ ~ +85℃ 7. Resistance Temp Coefficient: 50 ppm/℃ typical

1. Non-volatile memory auto loads last calibrated tap value at power-up without MCU reconfiguration 2. 1024 high-resolution taps enable fine digital trimming of analog signals with superior precision vs 32-tap pots 3. Multi-device cascading over I2C bus supports multi-channel gain trimming on single bus 4. Miniature SOT23 footprint space-optimized for compact sensors & portable acquisition hardware 5. Zero mechanical wear eliminates drift & aging for long-lifetime industrial equipment

1. Digital calibration circuits for op-amp analog gain stages 2. Auto compensation modules for sensor zero offset & full-scale output 3. Precision trimming of voltage references, digital adjustment of power supply output levels 4. Factory automatic calibration fixtures for portable medical testers & handheld instruments
