Working Principles
The X9119TV14Z digital potentiometer operates by using a series of resistive elements and switches controlled by an internal digital-to-analog converter (DAC). The resistance between the W (wiper) terminal and either the A or B terminal can be adjusted digitally by controlling the DAC output.
When a specific resistance value is programmed, the digital potentiometer adjusts the wiper position accordingly, effectively changing the resistance between the W terminal and the A or B terminal. The non-volatile memory ensures that the programmed resistance setting is retained even when power is removed.
