Usage Notes
1. Always attach an outside heat sink to use the chip. In addition, the outside heat sink must be fastened onto a
chassis for use.
2. Connect the cooling fin to GND potential.
3. Avoid short-circuit to V
CC
and short-circuit to GND, and load short-circuit. There is a danger of destruction under
a special condition.
4. The temperature protection circuit will be actuated at 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 its operation at V
CC
=
approx. 20 V.
6. Take into consideration the heat radiation design particularly when V
CC
is set high or when the load is 2
.
7. When the beep sound function is not used, open the beep sound input pin (pin 10) or connect it to pin 9 with
around 0.01
μ
F capacitor.
8. Connect only pin 9 (ground, signal source) to the signal GND of the amplifier in the previous stage. The
characteristics such as distortion, etc. will be improved.
