ClassD using LM311

lumanauw · 25th August 2007, 10:06 AM

Has anyone make classD based on 2 diagrams on LM311' datasheet?

It would be very nice to try it out. How much power we could get from this? I guess, not much. Maybe it is suitable for high-efficiency headphone amplifier? By the way, have never noticed that there were such schematics in the datasheet although I have used LM311 before. If I get some time I will build this circuit. Too bad I have no LMs in hand at the moment.

The lowpass input filter would need to be removed or increased in frequency for any real audio signal to make it through.
