Other Parts Discussed in Thread: TINA-TI, UA741,
Could you please provide the noise density data for LM741CN/NOPB?
It is not shown in the datasheet.

And, since Kai is looking at the output noise, that peaking to the right is the SSBW response peaking, not the input noise peaking.
Going a little further, TINA V11 had a library model with this header internally,
This one also does not have any 1/f effects, so kind of a bad model - seem to be quite a few like that out there,
Here was one of several recent efforts to asses and fix these kind of things,
I really appreciate for your kind support.
My customer is looking for P2P replacement for UPC151C-A. This looks very old part as well.
If UA741 is same as LM741C, the voltage noise information would be highly appreciated.
LM741 is similar schematic but different process. Nevertheless the uA741 noise should be close to what should be expected from LM741.
On these very old designs, the thermal noise is predictable (40nV/root Hz) and the 1/f noise can vary device to device. Here is two samples of uA741 voltage noise density. Ignore the spike at 60Hz.
I do not have LM741 samples
