This Edrawmax template illustrates the internal structure of an operational amplifier, which is divided into several key stages: the input stage, usually consisting of differential amplifiers for handling inverting and non-inverting inputs; the intermediate stage, which amplifies the signal; and the output stage, which delivers the final amplified signal. This block diagram simplifies complex electrical concepts into manageable components, making it an essential educational tool for students and professionals interested in electronics or electrical engineering.
