Need to amplify a small audio signal to play on an external speaker? The Micro Audio Amp by MitchElectronics can definitely help with that!

The Micro Audio Amp is a miniature audio amplifier based on the LM358 operational amplifier and uses a secondary push-pull amplifier for drivingexternal speakers. Audio signals can be fed into the AUDIOIN pin, and the potentiometer provides a variable gain control. While the output of this kitis directly connected to a small speaker for testing purposes, it can easily be modified with an external connector for use with larger speakers (suchas RCA connectors). This kit can also be connected to other MitchElectronics audio projects, such as the 555 Astable and the 555 Synth Punk, foramplification purposes.
