LM386 Audio Amplifier IC (2 in pack)

This low voltage audio power amplifier IC will make your audio projects a breeze. The gain is conveniently set to 20 internally which means you can use it to amplify your signals without need of many external parts! Furthermore you can easily set a specific gain between 20 to 200 by adding an external resistor and capacitor.

It is designed for battery powered applications and is found in many portable music gadgets such as mp3 players and radio sets. Of course you could also use it for boosting your sensor outputs (best results for signals in the audio frequency range).
