I've been reading about common mode distortion in op amps, and I think I understand the basic idea (although not the mechanism). I understand why it's a problem in a non-inverting configuration, and not in an inverting configuration.
I want to ask: does this only matter for common mode AC signals, or will a common mode DC offset degrade performance?
Specifically, would one need to worry about CM distortion in cases like the attachment?
My apologies in advance if this is a foolish question! Trying to educate myself, but I don't understand some of this very well.
