I used LMC7101 or OPA735 on a project I started a few months ago and had to put aside. For one reason or another I'm not sure which I used.
Now I have three versions of the board, and I populated two of them with one type amplifier and one of them with the other. At least, I think I did this much. My reasoning is because two of them have the same markings on the chip, one of them has a different set.
But how do I identify what kind of markings either chip uses? It's a SOT23-5 device and both say "NSC" The only difference is a squiggle and dot variance between the two!
I rechecked the datasheet, it says nothing for how they should be marked.
I searched google for photos of either chip, without any sufficient resolution.
I feel very silly asking "what chip did I use" but is there any way to identify these chips from the packaging labels?
Thanks! Any help appreciated.
