Working Principles

The DS1804Z-010/T&R is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a resistor network and a wiper terminal controlled digitally through an I2C interface. The resistance value between the wiper terminal and either the high or low terminal can be adjusted in 256 steps. The non-volatile memory ensures that the resistance setting is retained even when power is removed.
