Working Principles

The AD5260BRUZ50-REEL7 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 H/L terminal and the B terminal can be adjusted by sending commands through the I2C interface. The non-volatile memory ensures that the wiper position is retained even when power is removed.

Detailed Application Field Plans
