Working Principles

The MAX5385EZT+T is based on the principle of a digital potentiometer. It consists of a resistive element and a wiper that moves along the resistive track, controlled digitally through an I2C interface. The resistance value between the wiper and one end of the resistive element determines the output voltage. By changing the position of the wiper, the resistance and thus the output voltage can be adjusted.
