OPA2314: OPA2314AIDGKR

Part Number: OPA2314

Hi experts,

These were from Arrow.

During our inspection, we decapped a piece of OPA2314AIDGKR with DC:1915. The die did not show any markings that relates to a OPA2314 series.

Please check if this is a valid die.

    Hi Shawn,

    Arrow is an authorized distributor for TI. If the units came from Arrow then I would not expect them to be a counterfeit device. You can view our authorized distributors here.

    I am unable to view your images but if they came directly from Arrow then there should not be issues.

    Thank you,

    Hi Tim, 

    Yes. I understood. However, we need an objective statement. 

    Would appreciate your assistance to affirm that this is a valid die for OPA2314AIDGKR.

    Please see picture attached. 

    Thank you.

    Hi Shawn,

    I cannot comment if the die is counterfeit. If you suspect you received a counterfeit device, please take a look at our Anti-counterfeit webpage.

    Thank you,

    There is nothing suspicious about number on the die that seems unrelated to OPA2314. That in itself is not reason to suspect a non-TI product.
