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?

Jim, is that the spec for a ramp generator, or a scanning amplifier ?

It's an amplifier with less than 10KHz bandwidth (to get quick
settling), gain of 300, but it's essentially a DC signal.

the consequence may then be : a minimum Avol is required to achieve that
maximum percent linearity error relative to full dynamic range.
( and here I assumed a few implicit meanings..., disregarding the dynamics,
and only looking at the steady state or DC "final value".)
