4440 Amplifier Circuit Diagram. La4440 is a two channel audio power amplifier ic with inbuilt in dual channels enables it for stereo and bridge amplifier applications. A very high quality circuit with respect to its cost and ideal for beginners.
The amplifier provides high bass and its ideal for bass lovers. Hence we will be building a pcb at home by designing an audio amplifier pcb for this circuit. This is a 12 voltage amplifier.
Here ic la 4440 is wired as a bridge amplifier to deliver a 19 w rms on a 4 ohm speaker.
The ic is a dual channel audio power amplifier with low distortion and a good frequency range. This circuit uses an la4440 and some supporting components to give you much more power while retaining a small package that you can use. Back side of the same la4440 amplifier circuit board you can modify most readymade amplifier kit to la4440 bridge amplifier circuit by simply cutting some pcb tracks and adding some jumpers but that may vary board to board.
