Working Principles

The AD5245BRJZ5-R2 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 tap points along this ladder, the effective resistance between the input and output terminals can be adjusted.

The IC utilizes an I2C interface to receive digital commands from a microcontroller or other digital devices. These commands specify the desired resistance value, which is then translated into appropriate tap positions within the ladder network. The resulting resistance adjustment is highly accurate and repeatable.
