I don't know whether it is the right place for posting such question or not.
This question is opinion based so feel free to share your experience.
Background:
I had a year experience programming in C, had worked on micro-controllers like PIC for a little time and now working on nvidia-cards...
Re: Whats the purpose of these diodes in this driver IC
If the output is reversed biased then the B would short circuit and it will blows any way. Same is the case with C when input polarity is reverse bias. Correct if i am wrong.
You means to say diode A prevents the output transistor because...
Whats the purpose of these diodes in this driver IC
I would like to know the function of these 3 diodes in ULN2803A driver
A is used as a suppression diode but i didn't get the purpose of B & C.
Oops, I forgot that; I will add them now.
Pour is used as a ground in the above case.

On your helpful suggestions, I have modified the design as follows.
How can i solve this Right angle ?
You are right but my obsession was that the PCB trace pattern should look good :)
What i mean by this is that the connectors are not close to the edge of the board.
That's what I thought about first but by surfing different threads about 90/45-degree dilema i realized that it really doesn't...
I am a noob in PCB design and would like to know about the common mistakes beginners do while designing PCB. Here is a simple PCB which i had made.
The problem I am facing is that the connector on the bottom is NOT ON THE EDGE as shown here
If I drag these connectors down, the only problem...
I am trying to place these male headers on my PCB.
I have searched for its footprint and print it out on paper but when i try to place the actual header on printed page, there is a small distance error which results in the header pins not actually fitting in the holes.
The footprint i am...
What is input referred noise ? The gain shouldn't be Rf/Rin = 22k/10k=>2.2 in the above case ?
That was just to know how the OpAmp behaves when both the inputs are applied the same PD, i.e. Zero in this case

Edit: KlausS you are right, By neglecting the input bias current...
I have an OpAmp which states that its Input Offset Voltage is 2mV typical but I want to practically calculate the actual offset it will have at the room temperature. So I have connected the circuit in the following manner on the breadboard.
The Ouput voltage i got is 4.4mV, so does this means...
@Fvm: It means that the new OP wouldn't need it as the new ones don't use BJT's. I would like to make the physical circuit in order to know the offset effect it can cause on new OpAmps.
