Some manufacturers will cherry pick for you. Maybe the datasheet says
gain is 14 to 18 dB, and you order a batch that you want to be 15.5-16.5
dB.. They'll pick those out, but of course, now the remainder have a
hole in the distribution. Particularly when you're buying high-rel or
space grade, where they have to 100% test anyway.
