Hi,

Would you tell me what does the marking mean of MMAB? I know the G90 is device marking of LM4890MMX/NOPB.

    Hi Che yi su,

    I have been researching this. "MM" refers to the VSSOP and "G90" is the device marking.
    "AB" is manufacturing reference information and this cannot be shared only when needed. You have to share the reason why you need this information and more information about your application if you need it. Keep in mind that gets this information could take days or weeks.
