Sensor calibration  
The AD5270/AD5271 device wiper settings are controllable  
through the SPI digital interface. Unlimited adjustments are  
allowed before programming the resistance value into the  
50-TP memory. The AD5270/AD5271 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 resistance  
position (analogous to placing epoxy on a mechanical trimmer).  
GENERAL DESCRIPTION  
The AD5270/AD52711 are single-channel, 1024-/256-position  
digital rheostats that combine industry leading variable resistor  
performance with nonvolatile memory (NVM) in a compact  
package.  
The AD5270/AD5271 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 AD5270/AD5271 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.
