AD5293 Single Channel, 1024-Position, 1% R-Tolerance Digital Potentiometer

The AD5293 is a single-channel, 1024-position digital potentiometer (in this data sheet, the terms digital potentiometer and RDAC are used interchangeably) 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.

The AD5293 offers guaranteed industry-leading low resistor tolerance errors of ±1% with a nominal temperature coefficient of 35 ppm/°C. The low resistor tolerance feature simplifies openloop applications as well as precision calibration and tolerance matching applications.

The AD5293 is available in a compact 14-lead TSSOP package. The part is guaranteed to operate over the extended industrial temperature range of −40°C to +105°C.
