Analog Devices Inc. AD5175BRMZ-10

Description
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. It 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's 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 device 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.
The AD5175 is available in a 3 mm x 3 mm 10-lead LFCSP package and in a 10-lead MSOP package. It is guaranteed to operate over the extended industrial temperature range of -40°C to 125°C.
