LA4632
[Thermal Protection Circuit]
• The LA4632 includes an on-chip thermal protection circuit to prevent degradation or destruction of the IC due to
abnormal heating. If this IC's junction temperature (Tj) rises above 160°C due to and insufficient heat sink or other
reason, the thermal protection circuit will operate and gradually reduce the output signal level. This protection
function clears automatically as the temperature falls.
Notes on Printed Circuit Boards
When designing the printed circuit board pattern, keep the inputs and VCC, and the inputs and the outputs, away from
each other. (This is to prevent increased distortion, oscillation, and other problems.)
Notes on Heat Sink Attachment
Foreign matter such as metal chips must not be trapped between the IC's heat sink and the externally attached heat sink.
If a grease is used between the IC and the external heat sink, be sure to apply the grease evenly to the whole contact
surface.
Other Notes
The LA4632 is a BTL power amplifier IC. When connecting test equipment, the test equipment used for the input
system and the test equipment used for the output system must not share the same ground.
