DESCRIPTION
The DS1666 Audio Digital Resistor is a solid-state potentiometer composed of 127 digitally controlled
resistive elements. Between each resistive section and both ends of the potentiometer are tap points
multiplexed to the wiper. The position of the wiper on the resistance array is controlled by the CS , U/ D
and INC inputs. The taper of the DS1666 is shown in Figure 1.
