Got your attention, eh? 😀

Received this in today's spam load. May be interesting to some of you.

" --Improved packaging and layout minimizes op amp
distortion--
When using operational amplifiers, optimizing the
layout to achieve the lowest large-signal distortion
appears to be an abstract problem. A part might provide
distortion as low as -100 dB when evaluated on a board
provided by the manufacturer, but might get 10 dB worse
when it is plugged into the user's system. An ADI
engineer shows how they've solved that problem. "

Interesting, although in the experiment measurements presented
it seemed not make a difference until far above the audio band.

you are right on. This is one of those cases where people spend all the time, money and efforts to made in inaudioable improvement.

inaudioable to us non-golden ears anyway.
