CONSIDERATIONS TO KNOW ABOUT LOW-NOISE AMPLIFIER

It is really LM108 and LM112 (internally compensated) and there is really no trick there. It's 1nA input bias which can be rather stable with temperature as in most bipolar opamps simply because β essentially improves with temperature. Later iterations like LT1008/LT1012 or OP97 pushed it all the way down toThis amplifier is utilized as soon as th
