Hi Team,

    Hi Kai,

    Aside from the common mode range difference you noted, they are different in ESD rating:

    There is also a difference when stressed with large input transients. Version A may sustain damage from fast transients, as described in the datasheet:

    The two versions are otherwise identical in terms of electrical characteristics. They can be interchanged if these differences are not a concern.
