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.

FEATURES
128 position, digitally controlled potentiometer
Operates from a +5 volts power supply with TTL signal inputs
Wide analog voltage range of ±5 volts
Low-power CMOS
14-pin DIP or 16-pin SOIC for surface mount applications
Default position on power up sets wiper position to 10% of active digital taps (3% of the total end-to-end resistance)
Operating temperature range
  –  Industrial temp. range: -40°C to +85°C
