Working Principles

The MAX5166LCCM+ operates based on the principle of a digitally controlled potentiometer. It consists of a resistive element with three terminals - A, B, and W. The wiper terminal (W) can be moved along the resistive element, effectively changing the resistance between terminals A and B. This movement is controlled digitally through the I2C interface, allowing precise adjustment of the resistance value.
