Working Principles
The X9C103SZT1 is a digital potentiometer integrated circuit that emulates the functionality of a traditional mechanical potentiometer. It consists of a resistor ladder network and a wiper that can be digitally controlled. The wiper position determines the effective resistance between the H and L terminals.
The device utilizes non-volatile memory to store the wiper position, allowing it to retain its setting even when power is removed. This feature makes it ideal for applications where the resistance value needs to be maintained across power cycles.
Control inputs such as U/D (Up/Down) and INC (Increment) allow for precise adjustment of the wiper position. The chip select input (CS) enables communication with the device using a simple 3-wire serial interface.
