The AD5207 is a 2-channel, 256-position digital potentiometer with options for 10kΩ, 50kΩ, and 100kΩ. It features a low power shutdown mode with less than 5μA and operates on a single supply voltage of 2.7V to 5.5V. The product can be used as a replacement for mechanical potentiometers in applications such as stereo channel audio level control, gain and offset adjustment, and more.
The AD5207 provides two independent channels of digitally controlled resistance, each with 256 programmable steps. It replaces mechanical potentiometers and supports a 3‑wire SPI‑compatible serial interface, featuring power‑on reset to mid‑scale and a shutdown pin for ultra‑low power consumption.
The device operates from 2.7 V to 5.5 V, tolerates –40 °C to +125 °C, and offers 8‑bit resolution with ±1 LSB linearity. Typical applications include audio level control, instrumentation gain adjustment, programmable voltage‑to‑current conversion, and filter tuning.
