Good thought but I'm doing field testing of a signal conditioner to be attached
to an AVR in the future but for testing this weekend there is no AVR available.
Also, there will be another stage of conditioning after the op-amp prior to the
signal being fed to the AVR.

In doing some web searching I have discovered:

and

http://www.northcountryradio.com/PDFs/column009.pdf

which would seem to cover the first part of my query.

Still would like low cost recommendations for a single supply op-amp that can be
used for inputs from .1 to .6 vdc.

BTW: Even though this will eventually feed an AVR is there another list of
helpful, non-flaming folks that I should direct questions like this to?  I
realized that it's not directly AVR related.  So far I just subscribe to lists,
haven't ventured into newsgroups yet.
