Working Principles

The MAX7365EWA70+T is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a resistor network and a wiper that can be digitally controlled. The resistance value between the high terminal (VRH) and low terminal (VRL) can be adjusted by changing the position of the wiper.

The IC utilizes non-volatile memory to store the wiper position, ensuring that the resistance setting is retained even when power is removed. This feature is particularly useful in applications where the resistance value needs to be maintained across power cycles.

The digital potentiometer communicates with the microcontroller or other digital devices through the I2C interface. This allows for easy integration into digital circuits and enables precise control of the resistance value.
