Overview
The AD5232BRUZ10, produced by Analog Devices Inc., is a nonvolatile, dual-channel, digitally controlled variable resistor (VR) with 256-position resolution. This device functions as a solid-state replacement for mechanical potentiometers, offering enhanced resolution, reliability, and low temperature coefficient performance. It operates via an SPI-compatible serial interface and supports both single-supply (3 V to 5 V) and dual-supply (±2.5 V) configurations.
