Working Principles

The X9241AUSZ is based on the concept of a digital potentiometer. It consists of a series of resistive elements connected in a ladder-like configuration. By selectively connecting these elements, the effective resistance between two terminals can be adjusted digitally.

The resistance value is controlled by sending commands through the serial interface (SPI). The non-volatile memory ensures that the programmed resistance setting is retained even when power is disconnected.
