7. USAGE CAUTIONS
7.1 Caution on Shock Noise Reduction
When switching the power ON/OFF, use the external mute (approx. 200 ms) in order to minimize shock noise
(Refer to section 4.3 (2) Mute).
7.2 Supply Voltage
Pass data through the I2C bus only after stabilizing the supply voltage of the entire application system.

Remark
If the load capacitance of the output pins (SOT, ROT, LOT, MOR, MOL, FOR, FOL pins) exceeds
100 pF, parasitic oscillation may occur.
In this case, connect a resistor between the output pins
and the load capacitance. Bear in mind that the load capacitance is changed by wiring pattern on
the printed circuit board.
