Working Principles

The X9418WV24IT1 operates based on the principle of a digital potentiometer. It consists of a resistive ladder network and switches that can be controlled digitally. When a specific resistance value is programmed, the corresponding switches are activated or deactivated to achieve the desired resistance. The non-volatile memory ensures that the programmed resistance remains intact even after power cycles.
