    using a ADA4522-2 .
    

    +/-12VDC supplies
    

    sweeping system to test 3dB BW/
    

    signal into the ADA4522 (each config) ~ 1Vpp at 255KHz (see the blue in pic).
    

    output of invertcxonfig looks good.
    

    output of volt follower looks 'oscillatory/slewed.
    

    not sure why??????
    

    any ideas.
    

    meausufing at output of ADA4522 direct with 1Megohm scope probe (i.e. no long cables/capacitance/etc)
