Analog Devices Inc. AD5161BRM10-RL7

Description
The AD5161 is a compact, 256-position digital potentiometer that provides a solid-state alternative to mechanical potentiometers. It offers enhanced resolution, reliability, and low temperature coefficient performance. The wiper settings can be controlled via a pin-selectable SPI or I²C compatible digital interface, which also allows for reading back the wiper register content.
