The AD5272BRMZ-20 is a 1-channel 1024-position I?C Interface and 50-TP Memory Digital Rheostat that combines industry leading variable resistor performance with non-volatile memory (NVM). The AD5272 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 AD5272 device wiper settings are controllable through the I?C compatible digital interface. Unlimited adjustments are allowed before programming the resistance value into the 50-TP memory. It does 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).
