The Micro Audio Amp kit is a miniature audio amplifier based on the LM358 op-amp and uses a secondary push-pull amplifier for driving external speakers. Audio signals can be fed into the AUDIO-IN pin, and the potentiometer provides a variable gain control. While the output of this kit is directly connected to a small speaker for testing purposes, it can easily be modified with an external connector for use with larger speakers (such as RCA connectors). This kit can also be connected to other Mitch Electronics audio projects, such as the 555 Astable and the 555 Synth Punk, for amplification purposes.
The design of this kit has been chosen to demonstrate multiple circuit configurations, including inverting amplifiers with a virtual ground, AC coupling, and push-pull transistor amplifiers with cross-over bias. As such, the Micro Audio amp is an excellent kit for use in educational environments such as classrooms and remote practicals.
