Notes:
1. Cadj is for volume controller calibration purpose, the osc frequency is 1MHz when Cadj=100pF.
2. The DC block coupling capacitor (1µF) placed in every input and output pin must care the polarity,
the positive polarity side of cap must toward the higher potential for proper operation. If not may cause
abnormal pop noise during volume is changed.
