Back in the early eighties, I used the National Semi LH0033 and LH0063
hybrid wideband amps with nuclear particle counting tubes in X-ray
fluorescence spectrograph equipment. The old National data sheets for the
LH0033 specified them as "Fast", the LH0063 was specified as "Damn Fast".
I know these are in old National Linear data books I have at home, but these
parts are now long obsolete, and the NS site doesn't seem to have the data
sheets archived. Too bad, it was non-PC funny stuff.
Some of the early app notes from Linear Technology had some hidden gems as
well.
