Working Principles

The X9258TS24IZT1 digital potentiometer utilizes a series of resistive elements and switches controlled by an internal digital-to-analog converter (DAC). When a specific resistance value is programmed through the I2C interface, the DAC adjusts the switches to achieve the desired resistance. The non-volatile memory ensures that the programmed resistance remains even when power is disconnected.
