Rail-to-Rail Amplifiers Operate on 2.7V with 20μV Offset

摘要

The LT~(~R)1677 and LT1884 are the latest results of Linear Technology's quest forthe "ideal" Op Amp. Both of them will operate with supplies down to 2.7V, have only 20μV of input offset voltage and have rail-to-rail outputs. The LT1677 features very low noise, 3.2nV/ (Hz)~(1/2); the LT1884 features very low 150pA input bias current. Each of the two application circuits shown below take advantage of some particular subset of the features of these amplifiers.
