Each potentiometer provides 65 wiper positions with a 1 dB increment per step and device mute.

The DS1802 has two methods of device control, which include contact closure (pushbutton) inputs and a 3-wire serial interface for wiper positioning.

Key Features

  • Ultra- low power consumption.
  • Operates from 3V or 5V supplies.
  • Two digitally controlled, 65-position potentiometers including mute.
  • Logarithmic resistive characteristics (1 dB per step).
  • Zero-crossing detection eliminates noise caused by wiper movement.
  • Digital or mechanical pushbutton wiper control.
  • Serial port provides means for setting and reading both potentiometers wipers.
  • 20-pin SOIC and 20-pin TSSOP for surface mount.
