AD5161 is a 256-position SPI/I2C selectable digital potentiometer with four resistors options of 5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ. It is packaged in MSOP-10 (3 mm × 4.9 mm) and supports SPI/I2C interface. It can be powered by a single supply of 2.7 V to 5.5 V and works within a temperature range of -40°C to +125°C.
The AD5161 digital potentiometer provides 256‑position adjustment in a compact 3 mm × 4.9 mm MSOP‑10 package. It offers selectable SPI or I²C interfaces, full read/write of the wiper register, and the ability to daisy‑chain multiple devices.
Operating from a single 2.7 V to 5.5 V supply, the device consumes as little as 8 pA in shutdown and features a low temperature coefficient of 45 ppm/°C, making it suitable for portable and precision applications such as sensor biasing and mechanical potentiometer replacement.
