Working Principles

The X9279TV14ZT1 is a digital potentiometer that utilizes an integrated circuit to provide programmable resistance. It consists of a resistor array and a wiper that can be digitally adjusted through the SPI interface. The resistance value is determined by the position of the wiper along the resistor array.

During operation, the desired resistance value is sent through the SPI interface, and the IC adjusts the wiper position accordingly. The non-volatile memory ensures that the wiper position is retained even when power is removed, allowing for consistent settings upon power-up.
