GENERAL DESCRIPTION
The AD5272/AD52741 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.
