HwAoRrDk (how in the world do you pronounce that?)

The output for your ADC as taken directly from the op amp output is always low impedance, and buffered, its why I am such a fan of this circuit. no matter how you load that output, the feedback network is compensating it out.

Ah, okay, thanks. I wasn't sure. I thought maybe the high-value resistors in the feedback might affect things where otherwise lower-value ones would not.

P.S. Read the capital letters first. ;)

Board came in today!
Works great - at least on the bench :)

Thanks again for exposing me to this neat circuit, this was a lot of fun!
