Product Details
The AD5174 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 AD5174 device wiper settings are controllable through the SPI digital interface. Unlimited adjustments are allowed before programming the resistance value into the 50-TP memory. The AD5174 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 AD5174 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.
