AD5270 Description
The AD5270/AD52711 are single-channel, 1024-/256-position digital rheostats that bine industry leading variable resistor performance with nonvolatile memory (NVM) in a pact package. The AD5270/AD5271 ensure less than 1% end-to-end resistor tolerance error and offer 50-times programmable (50-TP) memory. The guaranteed industry leading low resistor tolerance error.
