Question
What are the important characteristics of an Operational Amplifier (OP-AMP)?
Open in App
Solution
The most important characteristics of OP−AMP are: (i) Very high input impedance or even infinity which produces negligible current at the inputs.(ii) Very high gain.(iii) Very low output impedance or even zero, so as not to affect the output of the amplifier by loading.
(i) Very high input impedance or even infinity which produces negligible current at the inputs.
