AD5272BRMZ-20-RL7

AD5272 is a single-channel, 1024-/256-position digital rheostat that combine industry leading variable resistor performance with non-volatile memory (NVM) in a compact package. This 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. It device wiper settings are controllable through the I²C-compatible digital interface. Unlimited adjustments are allowed before programming the resistance value into the 50-TP memory. Application includes 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, and sensor calibration.
