Working Principles

The MAX5480BEEE+T operates by digitally controlling the resistance between terminals A and B using a wiper terminal. The resistance value is determined by the position of the wiper along the resistive element. The digital potentiometer IC receives control signals through the serial interface (SPI or I²C) and adjusts the wiper position accordingly, allowing precise control over the analog signal passing through the potentiometer.
