Description
AI
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 I2C–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 trimmer).The AD5175 is available in a 3 mm × 3 mm 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.APPLICATIONSMechanical rheostat replacementsOp-amp: variable gain controlInstrumentation: gain, offset adjustmentProgrammable voltage to current conversionsProgrammable filters, delays, time constantsProgrammable power supplySensor calibration
