Rail-to-rail amplifiers operate on 2.7V with 20μV offset

Glen Brisebois

Abstract

The LT1677 and LT1884 operational amplifiers that operate with supplies down to 2.7V, have only 20μV of input offset voltage, and have rail-to-rail outputs, are described.

LT1884

The LT1677 and LT1884 are the latest results of Linear Technology’s quest for the “ideal” op amp.1 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/Hzimage; the LT1884 features very low 150 pA input ...
