OPA4277: About change of Rev C

Hide

Part Number: OPA4277

Hi Team,

I received a PCN for DS change of OPA4277UA/2K5(From Rev B to Rev C).

Could you please let us know why many parts have been changed?

We understand that no material or die Rev changes so we guess that the reason for the change are “Reflect the results of re-evaluation” and “typo correction”.

Is my understanding correct?

Regards,

Hi Hide,

there's a detailed "revision history" in the datasheet.

Hey Kai,

Thanks. I just found it. Interestingly we still have the old one up as well which is what I looked at first.

Hide,

Here is the revision history along with the link to the pds below.

Hi Chris-san,

Thank you for your response.

I have checked this “4.Revision History”.

However, I would like to know “Could you please let us know why many parts have been changed?”.

About 8 years later(From 2015 to 2023), many items have changed so I would like to know the reason for the sudden change.

Because, I can’t found this reason in the datasheet and PCN letter.

Regards,
