start with the basics ...

Historical aspect
01/01/70 00:00
Current directions
01/01/70 00:00
Maybe that's his confusion.
01/01/70 00:00
picky, picky,
01/01/70 00:00
Conventional Current Flow
01/01/70 00:00
But WHAT is flowing?
01/01/70 00:00
Please elaborate.
01/01/70 00:00
The >cause< is flowing...
01/01/70 00:00
A suggestion.

What do you think?
01/01/70 00:00
capacitors

It's there...
01/01/70 00:00
Just liked to make it clear..
01/01/70 00:00
How I would design it
01/01/70 00:00
if my load is resistive ...
01/01/70 00:00
Datasheet is a bit incomplete
01/01/70 00:00
clear till now...
01/01/70 00:00
if input is current? then output??
01/01/70 00:00
Current to voltage converter
01/01/70 00:00
Hhm...
01/01/70 00:00
I stand corrected

Mechanism of negative feed back
01/01/70 00:00
Thank You!
01/01/70 00:00
A bit more details are needed
01/01/70 00:00
Not for Application. Just learning.

Thank you.
01/01/70 00:00
start with the definition and go from there
01/01/70 00:00
whether offset can be calculated using a formula.
01/01/70 00:00
Calculation of Offset due to common mode voltage
01/01/70 00:00
Exactly !

01/01/70 00:00
That's not really op-amp specific.
01/01/70 00:00
true, the interesting fact here is
