The operation amplifier, as the name implies, is to do the operation of signal amplification, that is, the two input signals are respectively received to the positive and negative input terminals of the operation amplifier, the operation amplifier does the addition, subtraction, multiplication and division operations of the signal, and the output signal is the result of the signal operation. This feature was used in the early days as a computing component of analog electronic computers, and is now mostly used in signal amplification processing circuits. Magnification is used for multiplication and division, while addition and subtraction are used for comparators.
