Working Principles

The AD5231BRUZ100 is based on the concept of a digital potentiometer. It consists of a series of resistive elements connected in a ladder-like configuration. The wiper terminal can be moved digitally along the resistor ladder, effectively changing the resistance value seen between the wiper and the bottom terminal. This movement is controlled by the digital inputs provided through the I2C interface.
