Working Principles

The MAX5167NCCM+T is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a resistor ladder network and a wiper that can be digitally controlled. The wiper position determines the effective resistance between the two end terminals.

The device communicates with a microcontroller or other digital circuitry through an I2C-compatible serial interface. This allows the wiper position to be set digitally, providing precise control over the resistance value. The non-volatile memory ensures that the wiper position is retained even when power is removed.
