Not sure which one will make the better log converter yet!  LS312 has better
matching and stability with temperature specifications yet LS318 is listed
as a log conformance matched pair so we'll see by experimentation.

I like SMT for projects and one can always get a SOIC to DIL adapter for
prototyping.  I make tiny VCO modules that previously used the SSM2210
device in SOIC that I need to replace and these chips look like they could
be a drop in replacement.  George
