AD5272BRMZ-100

AD5272 is a single-channel, 1024-position digital rheostat that combine 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. The guaranteed industry leading low resistor tolerance error feature simplifies open-loop applications as well as precision calibration and tolerance matching applications. This 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. It is 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.
