Working Principles

The MAX5406EUM+T is a digital potentiometer that utilizes a resistor ladder network and electronic switches to control the resistance between its terminal A and terminal B. The wiper terminal, connected to the internal switches, moves along the resistor ladder in response to digital control signals. This changes the effective resistance between terminals A and B, allowing precise control over the output voltage or current in electronic circuits.
