Working Principles

The X9313ZSZT1 is based on the concept of a digital potentiometer. It consists of a series of resistive elements connected in a ladder-like configuration. By digitally controlling the taps along this ladder, the effective resistance between two terminals can be adjusted.

When the U/D pin receives an increment or decrement signal, the IC adjusts the tap position accordingly, changing the resistance value. The non-volatile memory ensures that the resistance setting is preserved even when power is removed.
