    Hello
    

    I have a question about the ADAU1979 analog input terminal ratings.
    The Analog Input Voltage (Signal Pins) is specified as -0.3V to 3.6V in the "ABSOLUTE MAXIMUM RATINGS" section on page 7 of the data sheet.
    

     
    


    However, ADAU1979 is differentially compatible with 4.5Vrms.
    At the differential 4.5Vrms input, I think each AIN pin has 2.25Vrms input.
    In this case, it will be 6.36Vp-p, and I think that it will exceed the rated value of the analog input.
    

    

    Can I use the differential 4.5Vrms input without any problems?
    

    I would be grateful if you could reply.
    

    

    Best Regards,
    Knj
