Working Principles

The AD5241BRUZ1M-R7 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 that connect these resistive elements, the effective resistance between two terminals can be adjusted.

The IC utilizes an I2C interface to receive digital commands from a microcontroller or other digital device. These commands specify the desired resistance value, which is then set by activating the appropriate switches within the IC. The non-volatile memory ensures that the resistance setting is retained even when power is removed.
