... DS1666-10 10K 24Ω DS1666-50 50K 122Ω DS1666-100 100K 243Ω 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 and inputs ...

... OPERATION The DS1666 has a total of 128 tap-points including the V segments exist between the V whose position is controlled via a 3-terminal control port. A block diagram of the DS1666 is shown in Figure 2. The 3-terminal port of the DS1666 provides an increment/ decrement interface which is activated via a chip select input. This interface consists of the input signals control a 7-bit up/down counter ...
