Working Principles

The AD5272BRMZ-50-RL7 operates based on the principle of a digital potentiometer. It consists of a resistive element with a wiper that can be moved digitally to change the effective resistance. The resistance value is controlled by sending commands through the I2C-compatible interface, which adjusts the position of the wiper. The non-volatile memory ensures that the resistance setting is retained even when power is removed.
