Working Principles

The MAX5480BEEE operates by digitally controlling the resistance value between terminals A and B. The digital potentiometer consists of a series of resistive elements connected in a ladder-like structure. By adjusting the tap position, the effective resistance between terminals A and B can be varied.

The control of the MAX5480BEEE is achieved through the SPI interface. The microcontroller or host device sends commands to set the desired resistance value, which is then translated into the appropriate tap position within the potentiometer array.
