RECOMMENDED POWER-UP SEQUENCE
The NJU72315 should be used under the condition that potential V- terminals are always the lowest potential.
Turn on VDD power supply first.
It is recommended that V- power supply turns on before or just same time that V+ power supply turns on.
Make sure to operate on the condition of V+ > VDD when it operates.

♦ Z/C:
♦ SS:
Zero Cross Detection circuit ON/OFF setting. Zero-crossing function is to change gain settings on a zero-crossing
of the input signal, and provides for reducing audible noise emanating during gain adjustments.
Soft-Step circuit ON/OFF setting. Soft-step function is to change gain settings step by step, and provides for
reducing zipper noise during gain adjustments.
