Hi Farid,

Does anyone know if the markings seem legit?

Based on the image, the IC's marking seems to be legit. I believe this is OPA2277UA grade (OPA2277U is the highest grade). I am unable to reveal the definition of these marking, but it seems to be matching to this part.

We received a partial real of the TI OPA2277U from a trusted supplier. 

TI parts have to be sourced by TI Authorized distributors or TI E-store in order to have the traceability. I do not know what a trusted supplier mean. If the supplier is not TI authorized distributor, we have to no ways to know where these parts come from. Please contact our Customer support team if you have additional questions.

Thank you Raymond.  This is helpful.

After I posted this, I was able to find older samples of the same parts, and the markings matched.  

Thanks again.
