    Hi,
    I tried to make an AC diffirential amplifier using an opamp (741).
    I try to use the ordinary opamp differential amp circuit that usually
    appears in the book and in the internet but it doesn't work. I also
    try to put a C block the DC but it also doesn't work. I wonder that
    anyone can point me out?

    Thank you
     
  2. Point me toward the "ordinary opamp differential amp circuit that
    usually
    appears in the book and in the internet", please. Perhaps we can
    figure out why it didn't work for you.
