Working Principles

The X9241AMS operates by digitally controlling the resistance value between terminals A and B. The potentiometer's wiper terminal (W) can be adjusted using the up/down control input (U/D) to change the resistance. The digital control is facilitated through the SPI interface, allowing for precise and convenient adjustment of the potentiometer's resistance.
