THE 2-MINUTE RULE FOR LOW-NOISE AMPLIFIER

It's LM108 and LM112 (internally compensated) and there is admittedly no trick there. It has 1nA input bias which can be rather secure with temperature as in the majority of bipolar opamps since β basically enhances with temperature. Afterwards iterations like LT1008/LT1012 or OP97 pushed it right down toBy using a substantial taste for excellent
