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 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 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 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.
