The open-loop gain of a certain op-amp is 210,000. It's common-mode gain is 0.16. Find the CMRR for this op-amp... Anyone know how to do this?

  1. 20log(210,000/0.16) = 122.3 dB or 1,312,000

    .


  2. Seems to me this should be easy to find in your text book unless you are in the middle of an exam and posting from a crackberry. :)

    Since I don't have my text book handy and it's been so long since school, I'm just glade I remembered what CMRR was.
