... ASAHI KASEI n Analog Volume (OPGA) The AK4560A includes the 0dB -50dB & MUTE analog volume with zero crossing detection for headphone and speaker. Zero crossing is detected on L/R channels independently. Zero crossing timeout (To) is proportional to sampling rate. To=512/fs@fs=48kHz=10.7ms. OPGA is not written during counting zero crossing timers. In case of writing control register continually, the change of OPGA should be written after zero crossing timeout and over ...
