Hi everyone,
I'm reading about opamps and trying to understand how they work. The subject is a bit over my head but it's a good way to learn.
Consider my use case: I have a digital circuit that generates two square waves from 0v to 2.5v that I would like to feed into an amplified speaker or headphones.
1) So I understand how to sum these 2 signals. But do I even need to amplify if I'm already going to an amplified speaker?
2) Let's assume that I do need to amplify. I read everywhere about inverting amplifiers using an op-amp. Using an inverting amp seems a bit complicated since I need to feed a negative voltage to the op-amp. My circuit is mostly digital so this is kinda exotic to me. Why is the inverting amp so popular? Would there be any downside for me to use the non-inverting version?
3) And if I do end up using the inverting amp, can I just connect the +vcc of the opamp to 0v and the -vcc to +5?
Thanks for the help
