GENERAL DESCRIPTION

The AD5293 is a single-channel, 1024-position digital

potentiometer¹with 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 open-

loop 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.

¹In this data sheet, the terms digital potentiometer and RDAC are used

interchangeably.
