AD5270BCPZ-100-RL7

AD5270 is a single-channel, 1024-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. 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 SPI digital interface. Unlimited adjustments are allowed before programming the resistance value into the 50-TP memory. It is used in applications 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.
