ANALOG DEVICES AD8021 Low Noise High Speed Amplifier for 16-Bit Systems handbook
The AD8021 is a very high performance, high speed voltage feedback amplifier that can be used in 16-bit resolution systems. It features low input voltage and current noise (2.1 nV/VHz typ and 2.1 pA/VHz typ) while operating at the lowest quiescent supply current among comparable high-speed op amps.
