Working Principles

The DS1806-100+ digital potentiometer operates by adjusting the resistance between its high and low terminals. The wiper output, controlled by the increment and up/down inputs, moves along the resistive element to change the effective resistance. The non-volatile memory stores the wiper position, allowing the device to retain settings even when power is disconnected.
