... GENERAL DESCRIPTION The WMS711x is a 128 non-volatile linear digital potentiometers available in 10KΩ, 50KΩ and 100KΩ resistance values. The WMS7110/1 can be used as a three-terminal potentiometer two terminal variable resistor in a wide variety of applications. The output of each potentiometer is determined by the wiper position, which varies in linearly between ...
