AD5272BCPZ-100-RL7

ANALOG DEVICES  AD5272BCPZ-100-RL7  非易失性数字电位器, 100 kohm, 单, I2C, ± 1%, 2.7 V

The is a single-channel Digital Rheostat combines industry leading variable resistor performance with non-volatile memory NVM. 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. The AD5271 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 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.
