4440 Amplifier Circuit. Laptop speakers are never loud enough to give satisfying listening. It s 12 volts sound intensifier utilizing is lm4440 ic 19 watts speaker.
This ic amplifier has 2 modes stereo amplifier and bridge amplifier mode according to datasheet it has following features built in 2 channels dual enabling use in stereo and bridge amplifier applications. Laptop speakers are never loud enough to give satisfying listening. In dual mode it gives 6 watts on each channel and in bridge mode 19 watts output.
This amplifier is capable to run easily up to 12 inch woofers.
We ve got structured it without pcb and utilized scarcely any capacitors with it. It has out class ripple rejection of 46db built in over voltage and surge voltage protection and deca 300 many more. Right now are visiting constructed a simple ic 4440 intensifier or an amplifier circuit yet the yield is extremely decent and high. La4440 amplifier circuit board la4440 is a two channel 6w monolithic linear ic power amplifier by using built in two channel we can amplify stereo audio signal and make bridge amplifier applications it will give 6w output when in dual stage and gives 19w in bridge stage.
