A simple audio amplifier circuit can be designed using the LA4460 IC . This circuit is very simple and require few external electronic components . The LA4460 IC is actually used for car radio or car audio power amplifier and may deliver output power up to 12 W. But in this circuit is only used 5W.
This amplifier circuit can be used for car radio applications , TV , or some other audio circuits that don’t require huge power .
