Working Principles
The X9279TV14IZT1 digital potentiometer operates based on the principle of resistive voltage division. It consists of a series of resistive elements connected in a ladder-like configuration. By adjusting the tap point along this ladder, the effective resistance between the wiper terminal and either end terminal can be changed. This adjustment is achieved by sending control signals through the SPI interface, which modifies the position of the wiper within the ladder structure.
