SOT-23 micropower, rail-to-rail operational amplifiers that operate with inputs above the positive supply are described.
SOT-23 operational amplifier
The only SOT-23 op amps featuring Over-The-Top operation—the ability to operate with either or both inputs above the positive rail—are the 55μA LT1782 and the 300μA LT1783. This feature is important in many current-sensing applications, where the inputs are required to operate at or above the supply. The wide supply voltage range, from 2.7V to 18V, gives the LT1782/LT1783 broad appeal as general purpose amplifiers, ...
