OPA4325: TI LOGO NOT FOUND ON DIE

Hi Jean,

They observed that there’s no TI logo or part# OPA4325 or similar markings on the die set.

TI logo is not always marked on a die which is the norm these days, as the die dimension is getting smaller and smaller. However, there should be a marking on the surface of die, I may be able to check it for you if you are able to provide a decapped image. The marking is for the internal use only and is not used for traceability purposes. 

TI's part traceability is not based on the internal marking on a Si die. TI is able to trace parts that are sold by the authorized TI distributors or TI e-store only. Since the part is purchased from TI Store, then customer should be confident that these are authentic parts. 

Please let me know if you have additional questions, 

Best,

Raymond

hi raymond, 

please see below of die image, yes we do know that parts are authentic but as this is our first time buying this part we wish to keep it as a record for future reference. 

Hi Jean,

You found the marking on the die. I will get it back to you next week, and it may take several days. 

Best,

Raymond

hi raymond, 

do you have any updates on this?

Hi Jean,

I am still waiting for reply. If this is urgent, please use the links provided by Marek. The application team does not have access to the low level design information, and we have to ask for other team for the support.
