The AD5207 is a dual channel, 256-position digital potentiometer that can replace mechanical potentiometers. It is available in 10kΩ, 50kΩ, and 100kΩ resistance values, and supports 2.7V to 5.5V single supply or -2.7V dual supply. It can be controlled via a 3-wire SPI compatible serial data input, and is automatically set to the midscale position during power-up.
The AD5207 digital potentiometer provides two independent channels, each with 256 programmable positions. It is offered with fixed resistor options of 10 kΩ, 50 kΩ, or 100 kΩ and features a low‑power shutdown mode (less than 5 pA) and a mid‑scale preset on power‑up. The device operates from a single 2.7 V‑5.5 V supply or a dual‑supply configuration (+2.7 V) and uses a 3‑wire SPI‑compatible serial interface for programming.
The datasheet includes electrical characteristics, pin descriptions, absolute maximum ratings, timing specifications, and an ordering guide. It also presents typical performance graphs such as bandwidth, gain, and power‑supply rejection. The AD5207 is supplied in a 1.1 mm thin TSSOP‑14 package and is rated for an industrial temperature range of –40 °C to +125 °C.
