Working Principles

The MAX5463EXK+T is a digital potentiometer that allows precise adjustment of resistance. It consists of a series of resistive elements connected in a ladder configuration. The wiper terminal (W) can be digitally controlled to tap into different points along the ladder, effectively changing the resistance between the wiper and the fixed terminal (B). The resistance value is determined by the position of the wiper.

The MAX5463EXK+T uses non-volatile memory to store the wiper position, ensuring that the resistance setting is retained even when power is removed. This feature is particularly useful in applications where the resistance needs to be maintained across power cycles.
