Other Parts Discussed in Thread: LM324, LM324-N

hi, are LM324AN and LM324AN/NOPB the same material? What does NOPB mean?

  • Hello,

    Welcome to the forum.

    LM324AN/NOPB was originally designed by National Semiconductor under product page LM324-N. So it is not the same material as LM324AN under product page LM324.

    NOPB means no lead.  The LM324AN is also lead free, see the "Quality, reliability & packaging information" links.
