Analog Devices AD5251/AD5252 Digital Potentiometer Datasheet
The AD5251 and AD5252 are dual‑channel, I²C‑compatible, non‑volatile memory digital potentiometers offering 64‑step (AD5251) or 256‑step (AD5252) resolution. They provide programmable resistance settings, non‑volatile storage, and support for linear increment/decrement and ±6 dB step commands, making them suitable for applications such as LED brightness control, sensor calibration, and power‑amp biasing.
The devices operate from a single 2.7 V to 5.5 V supply (or dual‑supply ±2.25 V to ±2.75 V), retain data for up to 100 years, and can be addressed on a shared I²C bus with up to four devices. Detailed electrical characteristics, timing diagrams, and ordering information are provided for design integration.
