    Hi,
    

    

    I want to use AD2S1210 for Resolver which has excitation voltage of 7Vrms and 10KHz frequency.
    

    

    Resolver Excitation Voltage : 7Vrms
    

    Resolver Output Voltage : 2V
    

    

    Can I use AD2S1210 directly of some gain factors are required?

      Pankaj,
      

      You will require voltage amplification on the EXC/EXCb pair to achieve the required 7VRMS excitation voltage.  I would also recommend that you verify the transformation ratio to ensure that the resolver output magnitude will also be within the range of the input otherwise you may observe loss of signal faults.
