DS1807 ATTENUATOR CONFIGURATION Figure 3 ZERO-CROSSING DETECTION The DS1807 provides many features for digitally controlled audio applications. Zero-crossing detection is useful in eliminating “zipper noise,” which is commonly associated with digital potentiometers. Zipper noise (because it sounds like a zipper) ...

When the master has received the ACKNOWLEDGE from the DS1807, the master can then begin to receive potentiometer wiper data. The value of the potentiometer-0 wiper position will be the first returned from the DS1807. Once the 8 bits of ...
