It's quite amazing what is going on in there, at so little power.
I've been using Maxim's MAX44246, which is similar.

Auto-zeroing op amps such as these, with input offset voltages of only a few microvolts and essentially no input offset voltage drift or 1/f noise, make designing a LOT easier for circuits where extreme DC precision is needed.
