Analog Devices Inc. AD5161BRMZ5-RL7

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