LA4440 IC Amplifier Circuit

In this article I would like to explain about IC 4440 amplifier circuit, it is operating on 12 volts but the output is very high and quality. This LA 4440 IC output can be getting 19 watts with 12 volts supply, this amplifier is widely used for car audio players why because this LA 4440 IC amplifier requires a single supply means (0-12v). It is cheap and the best amplifier for good results and also we can use this IC 4440 as stereo and as well as mono. Example: if built-in 2 channels (dual) enable use in stereo 6wx2=12w, and built-in as bridge amplifier output gets 19w. If you want to study this IC then you can check the 4440 IC datasheet pdf given below.

Working of Circuit:

As you can see above circuit diagram of IC 4440 is a 6w+6w stereo amplifier built around two loudspeakers and some other components like capacitors and resistors. from the above circuit 3 pin connector which is CON2 provides for Input signal (left- ground- right) channels, left channel audio input is connected to pin 6 of IC1 through the capacitor c1 which is 4.7µF/35V, and the right channel input is connected to pin 2 of IC1 through capacitor C2 (4.7µF/35V).

+12V power supply is connected to pin 11 of IC1, and electrolytic capacitor C12 (1000µF/35V) is connected between +12V and ground to act as a filter. In this article, you can find below LA4440 IC Datasheet Pdf
