ADC0804-N: Clarification on the die marking

jega sellan

Part Number: ADC0804-N

Tool/software:

Hello,

I have a part ADC0804LCN/NOPB with date code 1904+5 (I understand this device is obsolete). I would like to verify whether the die marking is genuine.

During die inspection, I could not find any TI or National Semiconductor logo. The die only shows the mask number ADC08A.

I have attached part images, die photos, and the package label for your reference. Could you please confirm if this is expected for this device?

Thank you, and I look forward to your feedback.

Regards,
J

Hi Jega,

On my side, I am only able to verify the top marking, and lot trace codes up to 12 months old. I recommend reaching out to the TI customer support center for further assistance.
