Working Principles

The X9420WV14ZT1 is based on the principle of a digital potentiometer. It consists of a resistive element divided into three terminals - A, W, and B. The wiper terminal (W) can be moved digitally along the resistive element, effectively changing the resistance between terminals A and W or W and B.

The position of the wiper is controlled by the digital inputs provided through the SPI interface. The non-volatile memory ensures that the wiper position is retained even when power is disconnected.
