... TAP points accessible to the wiper. The position of the wiper on the resistance array is controlled by the CS, U/D and INC inputs. The position of the wiper defaults to the 10% position on power up. The resolu- tion of the DS1666 is shown in Figure 1. DS1666, DS1666S DS1666, DS1666S Audio Digital Resistor ...
