Working Principles

The AD5273BRJ100-R2 is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a resistor network and a wiper that can be digitally controlled via the I2C interface. The resistance value between the wiper and either terminal can be adjusted by sending appropriate commands through the I2C bus. The non-volatile memory ensures that the wiper position settings are retained even when power is removed.
