" --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.
