Working Principles

The X9410WV24T1 is based on the concept of a digital potentiometer. It consists of a resistive ladder network and a wiper that can be moved digitally to adjust the effective resistance between the wiper terminal and either end of the ladder. The resistance value is determined by the position of the wiper.

The device utilizes non-volatile memory to store the wiper position, ensuring that the resistance setting is maintained even when power is removed. This makes it suitable for applications where precise resistance values need to be preserved across power cycles.
