Overview
The AD5292BRUZ-100, produced by Analog Devices Inc., is a single-channel, 256-/1024-position digital potentiometer. This device combines industry-leading variable resistor performance with nonvolatile memory (NVM) in a compact 14-lead TSSOP package. It is designed to operate across a wide voltage range, supporting both single-supply and dual-supply operations, and offers high precision with a maximum ±1% nominal resistor tolerance error. The AD5292 is ideal for applications requiring precise resistance adjustments and memory retention.
