Working Principles

The X9269US24IT1 digital potentiometer operates by using a series of resistive elements connected in a ladder configuration. The wiper terminal, controlled digitally, taps into this ladder at different points, effectively changing the resistance value seen between the high and low terminals. The resistance value is adjusted by sending commands through the I2C interface, and the non-volatile memory ensures that the resistance setting is retained even when power is removed.
