Working Principles

The X9315WST2 is a digital potentiometer that utilizes non-volatile memory to store resistance settings. It consists of a series of resistive elements connected in a ladder configuration. By digitally controlling the taps on this ladder, the effective resistance between the two terminals (H0 and H1) can be adjusted.

The potentiometer is controlled through a Serial Peripheral Interface (SPI), allowing for easy integration with microcontrollers. The resistance value is stored in non-volatile memory, ensuring that it remains unchanged even when power is lost.
