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.
