Hello,
If you go to this link:
http://en.wikipedia.org/wiki/Common-mode_rejection_ratio
and scroll all the way down to the bottom where they show the:
"Example: operational amplifiers"
section... we have:
I get +/-222mv ?
Am I doing the math wrong?

So for example, an op-amp with 90dB CMRR operating with 10V of common-mode will have an output error of ±316uV.
I get +/-222mv ?
Am I doing the math wrong?
