(Well, I don't know how the author is affiliated with AD though.)

A lot of bad advice and a few reasonable points. Curious to hear about your thoughts.

Which sections are bad advice in your opinion? I have been designing 40 input, 1.0 uV-stable ADC circuits for thermocouple measurements with their IC's (AD7793) and following their design guidelines. Still looking for ways to improve this circuit if you could offer better advice.

What would be a good article to read on this topic these days?

You can respin if you notice a problem. What about if it's a bit iffy but works fine on your bench - is it still going to work under different circumstances somewhere else?

I suggest a 1/4 size prototype for testing to see if you have the right track.

So... what's wrong with the article?
