LEAP#241 General Purpose 358 Amplifier


There’s always room on my bench for another general purpose amplifier. This is another LM358-based Op-Amp audio amplifier circuit, but it turns out to be not so useful. As-is, it suffers from two issues. First R8=1MΩ provides ridiculous gain, so most signals over 50mV or so slam to upper/lower output limits. Second, the push-pull output stage can’t deliver much power. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub hero_image
