Ok I have read up on op-amps at let me know if i'm getting this right.
Firstly if there is a more positive voltage applied to the + (noninverting) input the output tends to drive high.
If there more positive voltage applied to the - (inverting) input the output tend to drive low.
And the reverse. If a more negative voltage is applied to the + (noninverting) input the output drives low.
If there is a more negative voltage applied to the - (inverting) input the output drives high.
Now to work out the output I take the difference of the two input voltages and multiply it by the gain? How can I tell what the gain of a LM348 is?
Do you think I am missing any more important information concerning op-amps?
