Overview
The AD5231BRUZ10, produced by Analog Devices Inc., is a nonvolatile memory, digitally controlled potentiometer with a 1024-step resolution. This device performs the same electronic adjustment function as a mechanical potentiometer but offers enhanced resolution, solid-state reliability, and remote controllability. It is designed to operate as a true variable resistor replacement for analog signals, providing versatility and precision in various applications.
