This document is the AD5200/AD5201 digital potentiometer product manual, which introduces the product's features and application scenarios.
The AD5200 and AD5201 are programmable resistor devices that replace mechanical potentiometers in instrumentation, voltage‑to‑current conversion, programmable filters and impedance matching. They use a 3‑wire SPI‑compatible serial interface and are available in 10 kΩ or 50 kΩ resistance options.
The datasheet provides detailed electrical characteristics, absolute maximum ratings, pin functions, typical performance graphs, test circuit diagrams, package dimensions and ordering information for both devices.

The AD5200 provides 256 programmable positions, while the AD5201 provides 33 positions.
Both devices use a 3‑wire SPI‑compatible serial data input for programming.
The devices are guaranteed to operate from –40 °C up to +85 °C.
They can be powered from a single supply of 2.7 V to 5.5 V or from a dual supply with +2.7 V for AC or bipolar operation.
