Working Principles

The X9421WV14Z is based on the digital potentiometer concept. It consists of a resistive ladder network and a wiper terminal that can be digitally adjusted. The position of the wiper determines the output voltage, which can be precisely controlled by sending commands through the I2C interface. The non-volatile memory ensures that the programmed settings are retained even when power is disconnected.
