Working Principles

The X9317TS8 is a digital potentiometer that utilizes a resistor array and wiper terminal to provide variable resistance. It operates based on the principle of dividing the total resistance into multiple taps, allowing the wiper to select a specific tap and adjust the effective resistance.

The IC communicates with an external microcontroller using the I²C protocol. The microcontroller sends commands to increment or decrement the wiper position, thereby changing the resistance value. The non-volatile memory ensures that the wiper position is retained even when power is disconnected.
