The AD5175 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 I 2 C–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， a permanent blow fuse command freezes the resistance position （analogous to placing epoxy on a mechanical rheostat）。 The AD5175 is available in a 3 mm × 3mm 10-lead LFCSP package and in a 10-lead MSOP package. The part is guaranteed to operate over the extended industrial temperature range of −40°C to +125°C.
