Working Principles

The X9241AYPZ is a digital potentiometer that replaces traditional mechanical potentiometers in electronic circuits. It consists of a resistor network and a digital control circuit. The digital control circuit receives input signals from the interface (I2C or SPI) and adjusts the wiper position accordingly, effectively changing the resistance between the wiper terminal and the other terminals. The non-volatile memory ensures that the wiper position is retained even when power is turned off.
