ANALOG DEVICES AD5274BRMZ-20-RL7

AD5274 is a single-channel, 1024-/256-position digital rheostat. It combines industry leading variable resistor performance with non-volatile memory (NVM) in a compact package. It ensures less than 1% end-to-end resistor tolerance error and offer 50-times programmable (50-TP) memory. Rheostat wiper settings are controllable through the I²C-compatible digital interface. Unlimited adjustments are allowed before programming the resistance value into the 50-TP memory. They 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 wiper position. It is widely used in application such as mechanical rheostat replacements, Op-amp: variable gain control, instrumentation: gain, offset adjustment, programmable voltage to current conversions, programmable filters, delays, time constants, programmable power supply, sensor calibration etc.
