Working Principles

The MAX5480BEEE+ is a digital potentiometer that utilizes an internal resistor network and electronic switches to provide precise resistance control. It operates based on the I2C communication protocol, allowing digital commands to set the desired resistance value. The wiper terminal (W) connects to the desired point along the resistor network, effectively adjusting the output resistance.
