The AD5270/AD5271, members of the Analog Devices, Inc., digiPOT+™ family of potentiometers, 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) memory.
The guaranteed industry leading low resistor tolerance error feature simplifies open-loop applications as well as precision calibration and tolerance matching applications.
The AD5270/AD5271 device wiper settings are controllable through the SPI digital interface. Unlimited adjustments are allowed before programming the resistance value into the 50-TP memory. The AD5270/AD5271 do not require any external voltage supply to facilitate fuse blow and there are 50 opportunities for permanent programming. During 50-TP activation, a permanent blow fuse command freezes the resistance position (analogous to placing epoxy on a mechanical trimmer).
The AD5270/AD5271 are available in a compact 10-lead MSOP. The parts are guaranteed to operate over the extended industrial temperature range of −40°C to +125°C.
