1. GENERAL DESCRIPTION
The WMS714x is a 16 non-volatile linear digital potentiometers available in 10KΩ, 50KΩ and 100KΩ resistance values. The WMS7140/1 can be used as a three-terminal potentiometer or as a 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 VA and VB terminal according to the content stored in the volatile Tap Register (TR) which is programmed through Up/Down (Increment/Decrement) interface.
