OPA211, funny/peculiar graph in datasheet

Martin Griffith · Oct 20, 2007

Wow, my very own flame war.... Reminds me of my lottery experience...my
mum bought me a lottery ticket once that hit for $100--which makes me
the only person I know who's won something in a lottery without ever
having bought a ticket in his life. On the other hand, the $100 was
nicer.

I suspect that Fred got it right--that the G=1 and G=11 curves are
backwards, the labelling is messed up (distortion vs Vin not Vout), and
the nonlinearity in each case is from the output banging into the rail.
It seems to happen near 10V rms, which is +-14V peak, not bad going
for +-15V supplies. I'm still not designing anything based on those
curves, though.

Cheers,

Yep, Fred is OK, can't figure out if it was a Monday morning or Friday
afternoon datasheet

Yes, Mr. John Woogate

That's most unfair to John Woodgate, who is never anywhere near as
rude as Phil Allison.

Sorry Bill, meant it as the exact opposite to phil, appologies to Mr
Woodgate
