This is the best IC LA 4440 Laptop Audio Amplifier circuit diagram, the audio output from the laptop’s built-in loudspeakers is low. A energy amplifier is needed to obtain a high volume. This is a simple circuit to amplify the laptop’s audio output. The circuit is made around energy amplifier IC LA 4440 (IC1) along with a couple of other components. LA4440 is really a dual funnel audio
