Working Principles

The X9260TS24IZT1 operates by digitally controlling the resistance between its terminal A (H0) and terminal B (H1). The position of the wiper (terminal W) determines the effective resistance. The IC uses non-volatile memory to store the wiper position, allowing it to retain the resistance setting even when power is removed.

The resistance value can be adjusted by sending commands through the SPI interface. The IC responds to these commands by incrementing or decrementing the wiper position, effectively changing the resistance. The programmable nature of the X9260TS24IZT1 makes it suitable for various applications where precise resistance adjustments are required.
