Active Filters BPF TUNABLE

The AD5272 / AD5274 are single-channel, 1024-/256-position digital rheostats that combine industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package.The AD5272 / AD5274 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 AD5272 / AD5274 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 AD5272 / AD5274 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 AD5272 / AD5274 are available in a 3 mm × 3 mm 10-lead LFCSP package and in a 10-lead MSOP package. The parts are guaranteed to operate over the extended industrial temperature range of −40°C to +125°C.APPLICATIONS Mechanical rheostat replacements Op-amp: variable gain control Instrumentation: gain, offset adjustment Programmable voltage to current conversions Programmable filters, delays, time constants Programmable power supply Sensor calibration
