Introduction to Operational Amplifier: Characteristics of Ideal Op-Amp

In this video, the basic introduction of the Operational Amplifier (Op-Amp) has been given and different characteristics of ideal and real Op-amp (General Purpose 741 Op-Amp) has been discussed.
What is Operational Amplifier:
Operational Amplifier is one kind of Very High Gain Differential Amplifier with a single output.
Using this Op-Amp it is possible to perform different mathematic operations (by connecting few external resistors and capacitors) like addition, subtraction, integration, differentiation etc. And that is why it is known as Operational Amplifier.
Opamp consist of two inputs :
1) Inverting Input
2) Non-Inverting Input
The output of the Op-amp in open loop configuration is the product of open-loop gain and the difference between two inputs.
As, the gain of the Op-amp is very high, so in open loop configuration, even a small input signal will saturate the op-amp output. And the saturation voltage depends on the biasing voltages.
Characteristics of Ideal Op-amp:
1) Infinite Input Impedance
2) Zero Output Impedance
3) Infinite Voltage Gain
4) Infinite Bandwidth
5) Infinite Slew Rate
6) Infinite Common Mode Rejection Ratio (CMRR )
7) Zero input offset voltage (Output is Zero when input is Zero)
The timestamps for the different topics covered in the video is given below:
0:37 What is Operational Amplifier and Why it is known as Operational Amplifier?
1:17 Circuit Symbol of Op-Amp and Op-Amp in the open loop configuration
5:00 Voltage Transfer Curve of op-amp
7:24 Equivalent Circuit of the Op-amp
7:47 Ideal Op-amp characteristics
12:00 Characteristics or different parameters of General Purpose Op-Amp (741)
