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

Product Detail

The AD5272 is a single-channel, 1024-position digital rheostat with less than ±1% end-to-end resistor tolerance error and 50-time programmable memory.

The AD5272 supports a dual-supply ±2.5 V to ±2.75 V operation and a single-supply 2.7 V to 5.5 V operation, making it suited for battery-powered applications and many other applications.

The AD5272 uses a versatile I2C serial interface that operates in fast mode, allowing speed until 400 kbps. The device allows the selection of up to three different I2C addresses.

The EVAL-AD5272SDZ evaluation board can operate in single-supply and dual-supply mode and incorporates an internal power supply from the USB.

Complete specifications for the AD5272 can be found in the AD5272 / AD5274 data sheet.
