    What is an M8348 IC?

    Hello. I havee been examining a small test tool formerly owned by the Late Great audio designer James Bongiorno. It has a single 8 pin dip which is almost certainly some type of opamp.

    However I've had little luck finding useful info about it online.

    The only other lettering on it is 4250C/

    Thanks in advance for any help with this, lax
    Why don't you mine your own Bismuth,
    Mine your own Bismuth
    Mine your own Bismuth
    Why don't you mine your own Bismuth,
    So you won't be mining mine?

          Thanks, budm. So it is an LM4250.

          A photo would just show a small circuit board with an 8 pin DIP package and a handful of caps and resistors. Now I have a path to follow, thanks again, lax

              by Kush679
              Sorry,I'm using my phone right now and couldn't find any search bar to search on the topic of macbooks.
              Few weeks back(mid may),I had bought a MacBook pro m1 A2338. It belonged to my friend's younger brother who was a graphic designer,he gave me this MacBook without any icloud account linked to it and I had so much work during that times that I only used it for storage while traveling for shoots (I'm a photographer). So long story short,his brother got involved in a bad accident and was in coma and then fairly recently they pulled out his life support. I mistakenly did an erase Mac and...

              by TecnicaNTT
              Hi all,

              Need to identify a component that is broken.
              One I already identified using the forum but the other on the left is missing.
              I cannot give any lettering advise because the component is broken.
              Any help would be very useful.

              Motherboard model is: DAH98AMBAD0
