Not surprising, and good, I can get started with those.
The OPA1662 has the noise performance I ultimately want.
we also have lots of through-hole 74HC14
schmitt-trigger hex inverters,
Also good for getting started; thanks!
and i think we have a bunch of through-hole 3v3
regulators (and definitely 5v
7805s)

I'm actually looking for 5.5V, again with low noise.
if you're in on tuesday i'll help you find
things
I look forward to it! Are you also optimistic about SOIC-to-DIP

Two weeks ago (?) I chatted with Ivan about finding a way to
better index what's in the room. More motivation!
