I feel like I'm typically pretty good at reading op-amp datasheets... But this graph has me stumped. On page 8 or 7 (8th page, but it's labeled as 7) of the LMV324 datasheet, there are two graphs labeled as delta Vos vs CMR.

What is delta Vos? What is CMR? I know what Vos is, and I know what CMRR is, but I'm not sure this is referring to either of those? Change in offset voltage with respect to common mode voltage maybe? (which is the graph that I was looking for) But if that is what this graph is, why is common mode voltage being called CMR?

Very confused.

Well, delta Vos is certainly change in input offset voltage.

But, that is strange, because they never define CMR. CMRR does not fit, because that is the attenuation factor between changes on the power supply terminals and the output. (or, if you will, equivalent input offset).

Notably, the CMR axis is labeled with units = volts.

I am guessing that it should be CMV, common mode voltage.

To bad that Bob Pease isn't still around to tell us.

Input common voltage range =CMR?
