Product Overview

The DS1807+ is an addressable dual audio taper potentiometer in 14 pin DIP package. The device includes dual audio taper potentiometer having a logarithmic resistive characteristic (1dB per step). Each potentiometer has a total of 65 wiper positions including the mute position. Adjacent wiper positions are separated by 1 dB giving a total attenuation range of 64 dB. When the wipers are in the mute position, attenuation in excess of 90 dB is achieved. The DS1807 is controlled via a two-input serial synchronous interface that provides the capability of addressing up to eight different DS1807s. Addressability is obtained via communication protocol and three address select inputs A0, A1 and A2. Communication protocol allows for independent or simultaneous setting of the two potentiometer wipers. It replaces mechanical potentiometers with digital accuracy and reliability while its low-power circuits consume very little current.
  • Supply voltage range is 2.7V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • 2-wire addressable control interface
  • High performance audio volume and tone control with processor addressability
  • Zero-crossing detection eliminates zipper noise caused by discrete wiper changes
  • Data transfer in regular mode (100KHz clock rate) and fast mode (400KHz clock rate)
  • End to end resistance is 45Kohm at ± 20% tolerance and temperature coefficient is 750ppm/°C
