AD5272 Datasheet (Analog Devices) - I2C Interface and 50-TP Memory Digital Rheostat

AD5272, I2C Interface and 50-TP Memory Digital Rheostat

The AD5272/AD52741 are single-channel, 1024-/256-position digital rheostats that combine industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package.

The AD5272/AD5274 ensure less than 1% end-to-end resistor tolerance error and offer 50-times programmable (50-TP
