Working Principles

The X9421YS16Z is a digital potentiometer that utilizes integrated circuit technology. It consists of a resistive element and three terminals - high, wiper, and bottom. The resistance between the wiper and either the high or bottom terminal can be adjusted digitally using the I2C interface. The non-volatile memory ensures that the resistance setting is retained even when power is removed.
