Working Principles

The MAX5483EUD+T is a digital potentiometer that allows for precise control of resistance. It consists of a resistor array and a wiper switch, which can be digitally controlled using the I²C interface. The wiper position determines the effective resistance between the A and B terminals.

When a specific resistance value is desired, the microcontroller sends commands over the I²C bus to set the wiper position accordingly. The non-volatile memory ensures that the wiper position is retained even when power is removed.
