Question

Select the characteristics of an ideal operational amplifier.

1/ Zero gain for the common-mode input signal.


2/ Zero bandwidth


3/ Infinite gain for the differential input signal.


4/ Zero output impedance.


5/ Zero gain for the differential input signal.


6/ Infinite input impedance.


7/ Infinite bandwidth.


8/ Infinite output impedance.


9/ Zero input impedance.

Answer 1

Numbers 4, 6, & 7 are correct

Step-by-step explanation:

4- this allows the op amp to have zero voltage so that maximum voltage is transferred to output load.

6- this ensures that op amp doesn't cause loading in the original circuit, high input impedance would not deter the circuit from pulling current from it.

7- high difference between upper and lower frequencies.
