Hello,

I would like to know the meaning of the marking of the reference LMC7211AIM5/NOPB, which is located under the component. See attached.

" . 1C3 " or " dot 1C3 "

Thanks best regards,

The LMC7211AIM5/NOPB is obsolete and no longer supported. The current datasheet says that the marking should be "C00A"; "1C3" is not known on ti.com/packaging/en/docs/partlookup.tsp. How old is this chip?

Component LMC7211AIM5/NOPB is now obsolete, but has been replaced by the identical part number LMC7211AIM5X/NOPB, which has a larger packaging.

The top of the component is marked "C00A" and the bottom of the component is marked "dot 1C3".

Sorry, I did not realize that this is the bottom.

The meaning of the bottom marking is not public information.

Hello Benjamin,

The markings on the bottom are the orientation mark (dot), and the date code.

Due to counterfeiting, we cannot disclose the format publicly.
