In the conventional Serial Data Control Type Volume, Analog SW inside switches over simultaneously with Latch Condition Detector. And the operation completes. In this case the changing noise occurs at the time of Latch Condition Detector, the Analog SW switches over (Zero-cross Detector Strobe occurs) in the moment that the Analog Signal cross Signal Ground (0V). Latch Conditions Noise Factor when Signal is presentAudio Signal Signal GND(0V) Signal GND (0V) Analog SW changing Zero-cross Detector Strobe (Form signal from inside IC)Other,In the case of Audio Signal isn't inputted (No signal),even if only Zero-cross Detector Circuit detects Latch Condition, Analog SW doesn't switch over for the Audio Signal never cuts Signal Ground (0V).

Internal analog SW moves by [Zero-cross Detector Strobe] or [Compulsion SW of Timer Circuit]. For example, case of T=10msec. SW Changing Zero-cross Detector Strobe (Form signal from inside IC) In case of Pattern1, the Zero-cross Detector Strobe occurs with the Zero-cross Detector Function, and SW is switched. But in case of Pattern2, the Timer Function switches the Analog SW after T=10msec, for the Audio Input Signal didn't cut the Signal Ground after T=10msec which were set with the timer.
