DESCRIPTION
The DS1666 is a solid–state potentiometer which is set
to value by digitally controlled resistive elements. The
potentiometer is composed of 127 resistive sections.
Between each resistive section and both ends of the po-
tentiometer are 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.
The DS1666 Digital Audio Resistor is uniquely designed
to provide a potentiometer that is logarithmic rather than
linear across its entire range. The lower half of the po-
tentiometer advances 1% of total resistance for each
3% of scale advanced, providing for precise amplifica-
tion of low volume signals. The upper half of the poten-
tiometer advances 2% of resistance for every 1% of
scale advanced, providing for the lower resolution gain
required for high volume amplification.
