Dear Sir/Madan

We have purchased a TI part PCM1704U,we have them to do Die Verification testing,the Die marking is "BB ML.1001"And the top marking is " PCM1704 66M028M".

Can you help to verify is it A correct Die marking of this part?Is it a genuine TI part?

We need your support,dear.

I am looking forward to your reply.

    Hi, Ada,

    Welcome to E2E, Thanks for your interest in our products!.

    This is a genuine part from Texas Instruments. The BB marking corresponds to Burr-Brown®,  that was a company specialized in data converters. BB was acquired by TI on year 2000. 

    As long as you purchase TI parts from our authorized distributors, you should expect to receive genuine parts.

    Best Regards,

    Dear Diego

    Thank you for the verification the part is genuine.But if the Die marking ML.1001 match the data of PCM1704U?What i mean is if it's a valid die Marking?

    And also the chip marking,the "66M028M" if it's valid,dear?

    We are very much appreciated if you can help me to check.

    Dear Diego

    Thank you for the verification the part is genuine.

    But i want to know if the Die Marking "ML.1001" and the top marking,Lot# 66M028M is valid?Becuase as i know,it's obsoleted,the D/C is 2016+ so i feel quite worry.

    I really appreciated if you can help me to check and confirm it,dear.

    Many thanks for your help.
