ICs for Audio Common Use
I
Usage Notes
1. Always attach an outside heat sink to use the AN7555NZ. In addition, the outside heat sink must be fastened onto
a chassis for use.
2. Connect the radiation fin to the GND potential.
3. Prevent short circuit to V
CC
and short circuit to GND, and load short-circuit although the protection circuits for short
circuit to V
CC
and ASO are built-in.
4. The thermal protection circuit gets actuated when T
j
=
approx. 150
°
C, but it is automatically reset when the chip
temperature drops below the above set level.
5. The overvoltage protection circuit starts the protection operation at V
CC
=
approx. 20 V.
6. Take into consideration the heat radiation design particularly when V
CC
is set high.
7. When the beep sound function is not used, connect to GND the beep sound input pin.
8. Don't down below
0.3 V for the beep sound input pin.
9. When the AUX function is not used, open the AUX input pin.
10. Connect to signal GND of pre-stage amplifier only for the signal source ground.
There are the possibility of breakdown for the following conditions.
1. Reverse connection of the power supply pin and the GND pin.
2. Connection of the power supply between output pins at open condition of the power supply pin and the GND pin.
3. Short circuit to GND of output pin when the GND pin is open.
4. Short circuit to GND of above the three output pins at the same time with a shorting resistor which does not
operate the protection circuit.
5. Short circuit to GND of above the plus and minus output pins at the same time with a shorting resistor which does
not operate the protection circuit.
6. Short circuit to ground with shorting the RF pin and the output pin.
