LMV321: LMV321IDCKR differences on assembly sites

Hey Frank, 

Welcome to e2e! :) 

It is possible for LMV321IDCKR to have different die marking, I found this in the part lookup tool:

Here is the link for your convenience: https://www.ti.com/packaging/docs/partlookup.tsp#divline

I will let my colleague, Jerry, answer the rest of your questions. 

All the best,
Carolina

Hey Frank,

There is a PCN regarding the qualification of a new assembly test site.

In this change there are the following changes so there are possibilities for differences. However, the devices should all conform to the datasheet specifications. May I ask what drives this question?

Hi Jerry and Carolina,

Thank you for providing the information. We had been getting this part number under the same assembly site NFM and the die marking had been consistent. However, we have just got one batch from HFT which had another die marking.

We would like to know if that is normal or die marking from both assembly site should be identical.

Thank you.
