DESCRIPTION
The DS1807 Addressable Dual Audio Taper Potentiometer is a dual audio taper potentiometer having a
logarithmic resistive characteristic. 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 also
provides a zero-crossing detection capability. This capability eliminates noise caused by discrete wiper
position changes. 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 (3) address select inputs A0, A1, and A2. Communication protocol allows for the exact
positioning of the DS1807 wiper’s position. Additionally, communication protocol allows for
independent or simultaneous setting of the two potentiometers' wipers. Wiper positions can also be read
via the 2-wire serial interface.
