Overview
The AD5233BRUZ100-R7 is a quad-channel, nonvolatile memory, digitally controlled potentiometer produced by Analog Devices Inc. This device performs the same electronic adjustment function as a mechanical potentiometer but offers enhanced resolution, solid-state reliability, and remote controllability. It features four independent circuits, each with 64 taps, allowing for precise control over resistive elements. The AD5233BRUZ100-R7 is designed for a wide range of applications, including data acquisition, industrial control, and telecommunications.
