    Dear sirs,
    

    in AD8479 datasheet I could not find what is the maximum +Vs voltage that can be used in single supply operation (-Vs tied to ground).
    

    It is only specified the maximum dual supply voltage (i.e. +-18V).
    

    I would think that in single supply the maximum is 0/+36V but I would like a confirmation.
    

    

    Thank you,
    

    Riccardo

      Hi Riccardo,

      What you are thinking is correct. For AD8479, the absolute maximum would be 0/V+36V during single supply operation. 
      But please do take note that the datasheet only guarantees the electrical specifications at Vs= +/-15V. 
      Also, please do follow the guidelines about single supply operation stated in page 13 of the datasheet.

      That is all. 

      Thank you and Best Regards,.
      Sham
