AD5291 Overview
The AD5291/AD5292 are single-channel, 256-/1024-position digital potentiometers that bine industry leading variable resistor performance with nonvolatile memory (NVM) in a pact 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...
