DESCRIPTION
The DS1868 Dual Digital Potentiometer Chip consists of two digitally controlled solid-state
potentiometers. Each potentiometer is composed of 256 resistive sections. Between each resistive section
and both ends of the potentiometer are tap points which are accessible to the wiper. The position of the
