GENERAL DESCRIPTION  
The AD5291 and AD5292 are single-channel, 256-/1024-  
position digital potentiometers1 that combine industry leading  
variable resistor performance with nonvolatile memory (NVM)  
in a compact package. These devices are capable of operating  
across a wide voltage range, supporting both dual supply  
operation at 10.5 V to 16.5 V and single supply operation at  
+21 V to +33 V, while ensuring less than 1% end-to-end resistor  
tolerance error and offering 20-time programmable (20-TP)  
memory.  
The AD5291 and AD5292 device wiper settings are controllable  
through the SPI digital interface. Unlimited adjustments are  
allowed before programming the resistance value into the  
20-TP memory. The AD5291 and AD5292 do not require any  
external voltage supply to facilitate fuse blow, and there are 20  
opportunities for permanent programming. During 20-TP  
activation, a permanent blow fuse command freezes the wiper  
position (analogous to placing epoxy on a mechanical trimmer).  
The AD5291 and AD5292 are available in a compact 14-lead  
TSSOP package. The part is guaranteed to operate over the  
extended industrial temperature range of −40°C to +105°C.  
The guaranteed industry leading low resistor tolerance error  
feature simplifies open-loop applications as well as precision  
calibration and tolerance matching applications.  
1 The terms digital potentiometer and RDAC are used interchangeably.
