Working Principles

The X9429WS16IZ is based on the concept of a digital potentiometer. It consists of a resistor network and a wiper terminal that can be moved digitally. The position of the wiper determines the effective resistance between the B and A terminals. The device utilizes non-volatile memory to store the wiper position, allowing it to retain its setting even when power is removed. The I2C interface enables digital control of the potentiometer, providing precise adjustments.
