AD5270 Datasheet (Analog Devices) - SPI Interface and 50-TP Memory Digital Rheostat

AD5270, SPI Interface and 50-TP Memory Digital Rheostat

The AD5270/AD52711 are single-channel, 1024-/256-position digital rheostats that combine industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package.

The AD5270/AD5271 ensure less than 1% end-to-end resistor tolerance error and offer 50-times programmable (50-TP
