AD5175BRMZ-10-RL7 Single-Channel, Digital Rheostat with I2C Interface IC 

AD5175BRMZ-10-RL7 Single-Channel, Digital Rheostat with I2C Interface IC 

The AD5175BRMZ-10-RL7 is a single-channel, 1024-position digital rheostat that combines industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package. This device supports both dual-supply operation at ±2.5 V to ±2.75 V and single-supply operation at 2.7 V to 5.5 V, and offers 50-times programmable (50-TP) memory. The AD5175 device wiper settings are controllable through the compatible digital interface. Unlimited adjustments are allowed before programming the resistance value into the 50-TP memory. The AD5175 does not require any external voltage supply to facilitate fuse blow and there are 50 opportunities for permanent programming. During 50-TP activation, Na permanent blow fuse command freezes the resistance position (analogous to placing epoxy on a mechanical rheostat).
