    Hi,
    

    I need some help.
    

    As below picture picked from the datasheet. it said EPAD can connect to V- or leave floating, does ADA4666-2 also work if connected EPAD to GND?
    

    I mistakenly connected EPAD and GND, it sees the consumption of current rised.
    

    I will make a change in the next design,  and want to know what is the potential risk in my current circuit.
    

     
    

    Best Regards,
    Leo
