What about the input CMRR of the PGA2505. It's not mentioned in the datasheet.

Thank you

    Hello Carmelo,

    I am currently looking into this to provide you with more information.  I plan to measure a few devices in order to provide an estimate of CMRR; I will provide more detailed information by the end of the week.

    The datasheet discusses how the common-mode servo loop is able to improve CMRR for the device when the source is floating or has high common mode impedance; but, you are correct that a spec is not given in the datasheet.  

    Thank you,

    Regards,

    Luis
