That's a good idea. That's one issue that I have with a 10-bit ADC common to many MCUs, is the low voltage of 0.20 to 0.28 mV in the office. > Better yet, use the DS1620 (old revision) that is used on the Tbolt.

I like that idea as that can be bit-banged by a simple, small MCU on same board as the XO. Thanks for the thoughts, Mark!
