    Typ: 125uV, max 925uV

    Get outta here! They're just gaming the search results IMO

    That is a gigantic offset for a modern opamp.

    It's noisy too.

    RRIO, low offset, "high voltage", cheap, pick three I guess

    There are lots of different "modern" ops amps, optimised for lots of
    different jobs. The OPA4991 has lots of unique advantages, but low
    offset and low noise aren't any of them.
