You've got big problems with that DC gain of 300 assuming reasonable
full scale output range specified, seeing as how most of your stuff is
LV MOS. The parrots seem to be hung up on "best" straight line fit etc
when in fact the specification is maximum deviation of actual from ideal
as a percent full scale range...


"Linearity" is ususally not the same as absolute accuracy, but that's
a matter of application and definition.
