Working Principles

The MAX5166LCCM+T is a digital potentiometer that replaces traditional mechanical potentiometers in electronic circuits. It consists of a resistor network and a wiper that can be digitally controlled through the I2C interface. The resistance value between the RH terminal and the wiper changes based on the digital control signals received, allowing precise adjustment of resistance.
