DS1807E

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.
