Basics of Operational Amplifiers and Comparators Application Note 2021-03-26 1 © 2020-2021 Toshiba Electronic Devices & Storage Corporation Basics of Operational Amplifiers and Comparators Outline: Op-amps, also known as operational amplifiers, are used for voltage amplifiers, filters, phase shifts, and more. The comparator, also known as a voltage comparator, has a function to detect the high or low voltage with respect to the reference signal. This document explains the basic electrical characteristics (offset voltage, common-mode input voltage, open gain, common-mode input signal rejection ratio, frequency characteristics, etc.), absolute maximum ratings, and general usage (non-inverting amplifier, inverting amplifier).
