Shenzhen Mingjiada Electronics Co., Ltd. [Supply] AD5274BCPZ-100 (ADI) Digital Potentiometers - DigiPOT: Single Channel 256-Position Digital Rheostats, 1% Resistor Tolerance Error

AD5274BCPZ-100 is single-channel, 256-position digital rheostats that combine industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package.

AD5274BCPZ-100 ensure less than 1% end-to-end resistor tolerance error and offer 50-times programmable (50-TP) memory.

The guaranteed industry leading low resistor tolerance error feature simplifies open-loop applications as well as precision calibration and tolerance matching applications.

The AD5274BCPZ-100 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 AD5274BCPZ-100 do 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 wiper position (analogous to placing epoxy on a mechanical trimmer).

The AD5274BCPZ-100 is available in a 3 mm × 3 mm 10-lead LFCSP package. The parts are guaranteed to operate over the extended industrial temperature range of −40°C to +125°C.
