LM386 Based Low Power Audio Amplifier


LM386 is a low power audio amplifier IC designed for use in low voltage consumer applications. You can use this 8-pin IC to amplify the output signal from your mp3 player or computer audio output. The inputs are ground referenced while the output automatically biases to one-half the supply voltage. The quiescent power drain is only 24 milliwatts when operating from a 6 volt supply, making the LM386 ideal for battery operation.
