Make sure that the IC is free of any pin short-circuiting, ground short, and load short-circuiting. 2. Ground the radiation fin so that there will be no difference in electric potential between the radiation fin and ground. 3. The thermal protection circuit operates at a Tj of approximately 150°C. The thermal protection circuit is reset automatically when the temperature drops. 4. Make sure that the heat radiation design is effective enough if the Vcc is comparatively high or the IC operates high output power. 5. Connect only ground pin for signal sources to the signal GND pin of the amplifier on the previous stage.
