DS1807E集成电路（IC）的数字电位计规格书PDF中文资料

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.
