For some reason Amazon thinks that I want to buy a 4 pack of 10 bit ADC ICs. I can't think of why I would buy that.

Odds are good whatever µC I'd be plugging that into already has an ADC at about that resolution. If I needed to break out to an external chip for that I'd probably want something more like 24 bits (and then count on not using all of those bits because my circuit design skills aren't that great).
