Notes: 1. Standby

5V

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).

2. Muting

5V

Muting is turned off (output on) 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).

3. TAB (header of IC) connected to GND.
