MSL 3 so buy them in onesies and twosies if you're going to prototype
perhaps.. my experience is that chips with internal isolation barriers
are very sensitive if they get waterlogged, not just reflow but even hot
air or hand soldering may wreck them if they've sat out too long.

I asked our TI rep for the eval board and he sent me a long list of
questions that I must answer first. Too much hassle, so I'll use a
Murata part.
