Working Principles

The MAX5165LECM+T is based on the principle of a digital potentiometer. It consists of a series of resistive elements connected in a ladder-like configuration. By digitally controlling the taps along this ladder, the effective resistance between the input and output terminals can be adjusted.

The IC utilizes an I²C-compatible interface to receive digital commands from an external microcontroller or I²C master. These commands specify the desired resistance value, which is then set by adjusting the tap position within the ladder network.
