AD5293BRUZ-100-RL7 Datasheet PDF - ADI

GENERAL DESCRIPTION

●The AD5293 is a single-channel, 1024-position digital potentiometer with a <1% end-to-end resistor tolerance error. The AD5293 performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid state reliability, and superior low temperature coefficient performance. This device is capable of operating at high voltages and supporting both dual-supply operation at ±10.5 V to ±15 V and single-supply operation at 21 V to 30 V.
