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 ?

Jure Z.

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

So just overkill a 0.25% best-straight-line fit by 10:1 or so, and
they can't complain.

Sure thay can:
