Working Principles

The X9260US24IZT1 is a digital potentiometer that functions by adjusting its internal resistive elements based on digital commands received through the serial interface. It consists of a series of resistive elements connected in a ladder-like configuration. By selecting different taps along this ladder, the effective resistance between the wiper terminal and one end terminal can be varied.

The digital potentiometer utilizes non-volatile memory to store the resistance settings, ensuring that they are retained even when power is removed. This feature allows for easy recall of previous settings and eliminates the need for manual readjustment.
