Part Number: DAC7731


Hi, I'm having this part : DAC7731EC/1K (Date Code: 2325)

Datasheet: Marking :

DAC7731E

C

1) However my physical part marking does not have the "C". Was this remove as per the PCN. 

What is the C stand for and if my part marking is valid?

Thank you

    Hi,

    Yes, the Revision A part change removed the marking from the top of the package.

    The C just refers to the DAC7731EC or EC/1K. The C grade is the highest accuracy grade for the DAC7731E.

    Since the date code is mid-2023, the part is affected by the PCN and will be the EC/1K version.

    Thanks,
    Lucas
