Oh man, it's far from state of the art. "New" op amp features: - Crazy rail-to-rail input: some chips have onboard charge pumps to bias input stages such that you can input signals with common mode voltages far below and above the normal rails - Rail-to-rail output: probably the lowest hanging fruit of the "new" features, but still pretty costly - Stupidly high input impedance: 071 isn't completely blown out of the water but some of the new JFET opamps are nuts. I think there are like femptoamp class input currents these days. - Stupidly low offset voltage: I'm not even talking about the auto-zero ones, just regular old op amps have amazing performance these days.
