Working Principles

The AD5263BRUZ20-REEL7 is based on the concept of a digital potentiometer. It consists of a series of resistive elements connected in a ladder-like configuration. By digitally controlling the switches associated with each element, the effective resistance between two terminals can be adjusted.

The IC utilizes an I²C-compatible interface to receive digital commands from a microcontroller or other digital devices. These commands specify the desired resistance value, which is then set by activating the corresponding switches within the IC.

The nonvolatile memory feature allows the IC to retain the wiper position even when power is removed. This ensures that the resistance setting remains unchanged during power cycles.
