What is OP-AMP

Operational Amplifier-OP-AMP (LM741)


It is an IC with very high signal boosting power. Input resistance is very high, output resistance is low (75ohm).
Inside the IC is the differential amplifier on the input stage.
The main function of the operational amplifier is to amplify the input signal. The voltage gain can vary between 20,000 and 200,000.
It can upgrade efficiently up to 1MHz.
