Here's a first look at doing something interesting with an ADS1115 ADC module:  

For day to day tasks, it's already something of a work horse for Makers. But I wanted to push it to it's max settings to see if it's really useable for research level applications. The answer is a tentative yes, but only at the fastest 860 sample per second speed. And with small signals, EMI is more of a problem than the limitations of the ADC itself. I'm sure that's not news to any analog hardware hackers out there, but I'm kind of a digital kid who's still learning as I go along.
