The AD5291/2 are single-channel, 256/1024-position digital potentiometers1 with less than 1% end-to-end Resistor Tolerance error and 20-Time Programmable Memory. The AD5291/2 perform the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid state reliability, and superior low temperature coefficient performance. These devices are capable of operating at highvoltages; supporting both dual supply ±10.5 to ±15V and single supply operation +21V to +30V. The AD5291/2 offer guaranteed industry leading low resistor tolerance errors of ±1% with a nominal temperature coefficient of 35 ppm/ºC. The low resistor tolerance feature simplifies open-loop applications as well as precision calibration and tolerance matching applications.
