Op-Amp/Comparator Application Note - Rohm

op-amp. Generally, an op-amp is composed of three stages: the input stage, the gain stage, and the output stage. The input stage is configured with a differential amplification stage that amplifies the differential voltage between the two terminals. In addition, it does not amplify the common-mode signal component (a condition where no ...
