TLV272-Q1: TLV272QDRQ1 marking

Hello,

The topside markings are used to trace device, lot, date, and other information.  For these devices, everything looks legitimate to me.

I could not immediately find an explanation for the bottom side markings.  However, I think the following e2e threads are relevant and should help to answer your question.

• Bottom side pat marking question - Can you tell me what these markings mean?
• INA114: INA114 bottom marking
• OPA2340: back side marking

Please let me know if anything is unclear or if you have a follow-up question.

Regards,
Daniel
