Part Number: OPA4251

We are trying to get some min/max numbers onf voltage for OPA4251. Can someone please advise?

    Hi Dan,

    The equivalent spec for Voltage Gain (Large Signal) is AOL. This spec can be found on the datasheet (see below).

    The output swing values are also in the datasheet, but is only specified with 20kΩ and 100kΩ loads.

    The slew rate is also in the datasheet, but only the typical value is specified, which you seem to have noted (0.1V/us). 

    I would also note that the OPAx241 is optimized for a 5V supply, while the OPAx251 is optimized for a 15V supply. Depending on your application, you might want to consider the OPAx241 instead of the OPAx251.

    Please let me know if you have further questions.

    Best regards,
    Carrie
