This is the best IC LA 4440 Laptop Audio Amplifier schema 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 schema to amplify the laptop’s audio output. The schema is made around energy amplifier IC LA 4440 (IC1) along with a couple of other components. LA4440 is really a dual funnel audio energy amplifier.

It’s low distortion over an array of low to high wavelengths with good funnel separation. Built-in dual channels enable it for stereo system and bridge amplifier programs. In dual mode LA4440 gives 6 w per funnel as well as in bridge mode 19- watt output. It’s ripple rejection of 46 dB. The audio result can be recognized by utilizing two 6-watt loudspeakers.
Connect hooks 2, 6 and ground of IC1 towards the stereo system jack which is combined with laptops. Assemble the schema on the general-purpose PCB and enclose inside a appropriate cabinet. The schema works off controlled 12V power supply. It’s suggested to make use of audio input socket within the schema board. Make use of a proper warmth-sink for LA4440.
