OPA132: Reason for changing Vcm

Part Number: OPA132

Tool/software:

Hi, staff

In Rev.C (SBOS504C) of OPA132, the common-mode voltage has been changed to (V+)-3.5V.
In Rev.B, it was (V+)-2.5V.
Why has it dropped by 1V?

regards
cafain

    Hi Caifan,

    The OPA132 has gone through a manufacturing change, these changes are due to a transition of the OPA132 from our 150-millimeter factory to the more efficient 200mm manufacturing process, to ensure supply continuity. 

    The datasheet section 9 revision history on page 17 lists the changes, corrections from revision B to revision C.  Please let me know if you have questions.

    Thank you and Kind Regards,

    Luis
