Note: 1. Standby

Power is turned on when a signal of 3.5 V or 0.05 mA is impressed at pin 2.
When pin 2 is open or connected to GND, standby is turned on (output off).

5 V

2. Muting
Muting is turned off (output off) when a signal of 3.5 V or 0.2 mA is impressed at pin 10.
When pin 10 is open or connected to GND, muting is turned on (output off).

5 V

3. DC-DC converter (Booster)
DC-DC converter (Booster) in IC is turned on when a signal of 3.5 V over or 0.04 mA over is

impressed at pin 13, and get large max output power.
When pin 13 is open or connected to GND, DC-DC converter (Booster) is turned off.
This IC is generated noise, because built-in DC-DC converter (Booster).
Consequently if you use radio tuner (AM), I recommend DC-DC converter (Booster) off.
