Trying to work out the current being drawn from an op amp.
What is the I/P offset current and the i/p bias current?

When you are not in an educational circle it is harder to learn/teach yourself.
I have read the rules, I understand the conditions.

cbarn correctly answered your question. One thing to note, however, is that there must be a DC signal path to supply these currents. Or in other words, you can't have only capacitors hanging on your 2 inputs.

Cheers guys for the help. Is there any other advice that you could give me on how to look at these data sheets/learn how to translate the information on them? Or is it just something that I will have to pick up with experience?
It is interesting to look at things in this kind of depth I must say though.

It may be hard to find, but it really gives a good insight into why opamps are designed the way they are, and what some of the trade-offs in design are dependant on.
I like it also, because all of the math is in algebra, no integral calculus like some references.
