[sci.electronics] How linear is an op amp?

If you browse through the data books, instrumentation amplifiers normally
have a linearity specification. Vanilla op amps normally don't. If I build
the classical instrumentation amplifier from 3 op amps, what sort of
linearity should I expect? How should I think about this problem? (I
suspect a trip to the lab is the right answer.)
