OPA313: Confirm top/ device marking

Nitesh Bhurke

Part Number: OPA313

Hello,

We have used the OPA313IDCKR part in one of our designs. We facing one issue regarding the device/ top marking of this IC. We have checked the datasheet of the IC, but there are mentioned two different device markings of OPA313IDCKR IC as shown in the attached images.

Can you please confirm which of the device marking or top markings is correct?

The table on p. 2 is created by hand, so it is likely that the error is there.

And the part marking lookup database confirms that SIE is DBV, SIF is DCK.
