Hi all,
I am in need of some help,
I cannot find the compnent above (top left IC) in the TI catalogue.
It is supposed to be am opamp, but I could only find the OPA338, which doesn't come in the package as for the photo.
Any suggestions?
Many Thanks
Riccardo
Hello Ricardo,
I am having some difficulty determining the characters in the top row.
Is it I388A or I888A?
Please clarify.
Thank you,
~Leonard
Hi Richard,
the first character is the letter I ; if it was the number 1 it would have the slanted line at the top and line at the bottom.
Using the Part Marking tool: https://www.ti.com/packaging/en/docs/partlookup.tsp?partmarking=i33
and various combinations of 3 and 8, the only match is the
Part number: |
Marking: I333A |
Package | Pins DRG | 8 |
https://www.ti.com/product/INA333
Any chance you can get a schematic of the board?

Hi Ricardo,
As far as I can tell these are all QFN packages, and there is no QFN package for OPA338.
Unfortunately we don't have any database that allows us to search for product markings from all the devices across the company. If we knew a part number, we could check the marking but since we don't have numbers, I don't think there's much we can do, sorry.
Regards,
Mike
Thanks, that is a step forward. I am waiting to get my hands on the board to draw a schematic diagram
