AD5293BRUZ-100

The AD5293 is a single-channel, 1024-position digital potentiometer(in this data sheet, the terms digital potentiometer and RDACare used interchangeably) with a <1% end-to-end resistor toleranceerror. The AD5293 performs the same electronic adjustmentfunction as a mechanical potentiometer with enhanced resolution,solid state reliability, and superior low temperature coefficientperformance. This device is capable of operating at high voltagesand supporting both dual-supply operation at ±10.5 V to ±15 Vand single-supply operation at 21 V to 30 V.
