yep. But Maxim and CS have a more agressive "sampling" strategy :-)
i have Maxim MAX120, MAX 122 and MAX 198 (all in handy narrow DIP package),
and Cristal CS4222(*2), CS5394(*2) and CS5396(*1). The 539x are in
SMD package with a 50mil pin spacing but the 4222 is in 25mil, i can't solder
something *that* thin.

There's also a CS5524 but it is limited to 1KHz sampling :-)
And a TI 8-bit 10MHz ADC, too.

they are often distributed for free along with the samples. I have a small
pile of papers related to that (implementation notes, data sheets...)

you'll have to prove it ;-P do you have a SMD soldering station at home ?
(i don't but that could be useful sometimes ;-D)
