AN5278
ICs for Audio Common Use
s Usage Notes
1) External heatsink is needed when used. External heatsink should be fixed to the chassis.
2) Fin of the IC can be connected to GND.
3) Please prevent output to VCC short, output to GND short and load short to GND.
4) The temperature protection circuit will operate at Tj around 150 °C. However, if the temperature decreases, the
protection circuit would automatically be deactivated and resume normal operation.
