1. Be sure to use the circuit with an external heat-sink and fix the external heat-sink on chassis when using it.
2. Connect the heat radiating fin to GND potential.
3. This IC has built-in protection circuit against short-circuit to V
4. The thermal protection circuit operates at T
5. The over voltage protection circuit operates at V
6. Be especially careful to heat radiation design when used at an increased V
7. Connect the beep sound input pin to GND when the beep sound function is not used.
8. Do not lower the beep sound input pin below
9. Keep AUX input pin in open state when AUX function is not used.
10. Connect only GND pin (signal source) to the signal GND of the amplifier in previous stage.
1. If the power supply pin and GND pin are connected in reverse to the power supply.
2. If the power supply pin and GND pin are in open state and the power supply is connected across the output pins.
3. If the output pin is grounded when GND pin is open.
4. If more than three output pins are grounded to the earth at a time with more than 1.3
5. If plus and minus output pins are short circuited to the supply line at a time with more than 1
6. If the RF pin and the output pin are short circuited and short-circuited to the earth.
There is a possibility of device destruction under the following conditions;
