Working Principles

The MAX5402EUA+ operates based on the principle of a variable resistor. It consists of a resistive track with a wiper that moves along it. By adjusting the position of the wiper, the effective resistance between the wiper terminal (A) and the other terminals (B, C, D, E) can be changed. This variation in resistance allows precise control over the electrical signals passing through the potentiometer.
