Description

The AD5293BRUZ-20 is a digital potentiometer belonging to the category of electronic components. It is a single-channel, 1024-position resolution device with a < 1% end-to-end resistor tolerance error. Specifically designed to replace mechanical potentiometers, the device enables enhanced resolution, solid-state reliability, and superior low temperature coefficient performance. It can operate at high voltages, supporting both dual-supply operation at ±10.5 V to ±15 V and single-supply operation at 21 V to 30 V.
