    For my class we have a project where we need to design an AB power amplifier. I would like design one as simple as possible and preferably uses an op amp. As far as understanding these things right now I'm lost. Can someone post a schematic that will match the specifications I will list and explain to me how the circuit is working?
    Input Signal: nominal "line" level (-10 dBv)
    Output Power: 3W rms <+Pout<= 25W rms
    DC Output Voltage: 100 mV maximum
    Total Harmonic Distortion (THD): <= 1%

    Gee, you start off by saying that you would like to design an amplifier, but then you want someone else to design it for you, and then explain it to you.

    Why don't you start off by researching operational amplifiers?

    Look in our E-books, in Volume III. There are links to our E-books at the top of every page on this site.
