When both the inputs are same an op amp ideally should have an output?
Since, the difference in input voltage on both inputs is zero. Therefore, output of an ideal op-amp is also zero.
What are two inputs to an operational amplifier?
An Operational Amplifier is basically a three-terminal device which consists of two high impedance inputs. One of the inputs is called the Inverting Input, marked with a negative or “minus” sign, ( – ). The other input is called the Non-inverting Input, marked with a positive or “plus” sign ( + ).
What are the two most important parameters to be considered while choosing an op amp?

- Gain bandwidth product (GBP)
- Voltage follower.
- Inverting operational amplifier.
- Non-inverting operational amplifier.
