I have a specification for an amplifier design that says "0.25%
linearity".

I can't seem to lay my hands on a precise definition of what that
means.

Likewise... How to calculate?

Probably peak deviation from best straight-line fit, as a percentage
of full-scale swing. Most people would use half of rail-rail output
swing (ie, peak, not p-p) as the denominator.

That's sort of what I was musing. Now to implement it in PSpice.
