Working Principles

The DS1806E-100+T&R is a digital potentiometer that utilizes a programmable resistance element to adjust the electrical characteristics of a circuit. It operates by changing the resistance value between the W (wiper terminal) and either end terminal, controlled by the U/D (up/down control) and INC (increment control) pins. The non-volatile memory ensures that the resistance setting is retained even when power is disconnected.
