LA4440 Audio Amplifier Circuit
Simple audio amplifier based on IC LA4440. It takes the headphone level output from your computer and amplifies a pair of external speakers. If you’re listening to music or movies on laptops and computers, this is a useful little project.
Notebook speakers are never strong enough to provide a satisfying listening experience. They give users the ability to listen to anything, but they’re too bad for anything like music or movie soundtracks.
The output of the laptop built into the speakers is very weak, and the LA4440 audio amplifier circuit manages this low power with extra amplification.
