GENERAL DESCRIPTION

The AD5291 and AD5292 are single-channel, 256-/1024-position digital potentiometers1 that combine industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package. These devices are capable of operating across a wide voltage range, supporting both dual supply operation at ±10.5 V to ±16.5 V and single supply operation at +21 V to +33 V, while ensuring less than 1 end-to-end resistor tolerance error and offering 20-time programmable (20-TP) memory.

The guaranteed industry leading low resistor tolerance error feature simplifies open-loop applications as well as precision calibration and tolerance matching applications.
