The AD5204/AD5206 is a 4/6-channel digital potentiometer with 256 positions and independent programming. It can replace mechanical potentiometers and has features such as 10kΩ, 50kΩ, 100kΩ, 3-wire SPI-compatible serial data input, +2.7V to +5.5V single supply, -2.7V dual supply, power ON midscale preset.
The AD5204 and AD5206 are 4‑ and 6‑channel, 256‑position digitally‑controlled variable resistor devices that replace mechanical potentiometers. Each channel provides a programmable resistance between terminals A‑B, A‑W, or B‑W with selectable nominal resistances of 10 kΩ, 50 kΩ, or 100 kΩ. The devices use an SPI‑compatible 3‑wire serial interface and support mid‑scale power‑on preset and shutdown modes.
The parts are offered in PDIP‑24, SOIC‑24, and TSSOP‑24 packages and operate over an industrial temperature range of –40 °C to +85 °C with a single‑supply voltage of +2.7 V to +5.5 V (or dual supply). The datasheet includes detailed electrical characteristics, absolute maximum ratings, pin‑out tables, timing diagrams, and mechanical dimensions.
