The AD5291/2 are single-channel, 256/1024-posiTIon digitalpotenTIometers1 with less than 1% end-to-end ResistorTolerance error and 20-TIme Programmable Memory. TheAD5291/2 perform the same electronic adjustment funcTIon asa mechanical potentiometer with enhanced resolution, solidstate reliability, and superior low temperature coefficientperformance. These devices are capable of operating at highvoltages;supporting both dual supply ±10.5 to ±15V and singlesupply operation +21V to +30V.The AD5291/2 offer guaranteed industry leading low resistortolerance errors of ±1% with a nominal temperature coefficientof 35 ppm/ºC. The low resistor tolerance feature simplifiesopen-loop applications as well as precision calibration andtolerance matching applications.
