AD5232BRUZ10-REEL7

Digital Potentiometers Overview

The AD5232BRUZ10-REEL7 is a dual-channel, nonvolatile digital potentiometer featuring 256-position resolution and a nominal terminal resistance of 10 kΩ. It operates on a single supply voltage ranging from 2.7 V to 5.5 V or a dual supply of ±2.25 V to ±2.75 V. The device utilizes an SPI-compatible serial interface for programming and includes 14 bytes of general-purpose user EEMEM. Wiper settings are retained in nonvolatile memory with a typical data retention of 100 years at 55°C junction temperature.
