LM386 audio amplifier circuit and PCB >>

This is associate amplifier which will be used with atiny low nine potential unit Battery Operated,Current use as very little as five milliamps.And amplification up to five hundred mW.
Which is spare to expand the sound from a sound concerning or the CD Walk Man bent the tiny speakers clearly.
When coming into the ability provide 9-volt circuit IC1 range LM386 electronic equipment IC size is 300-800 mW, looking on the ability provide circuit with,This is from 4-15 volts.

Once entered into the input pin three,The non inverting pin to electronic equipment non-return part.C1 are going to be served cut out the noise input to ground.And C2 will increase the speed of electronic equipment,C2 is to feature additional price.But if the C2 an excessive amount of distortion (the C2 mustn't exceed 100uF).The output of IC1 is out of the pin five through C4 coupling audio signals to raised and DC block and not passed to the speaker.For the audio portion will be fed back through R2 and C3 to the high frequency response higher.Electronics Circuit Application
