    Hello Devendhiran,

    There is no impedance due to the fact that the input bias current does not act like a resistance.  This is due to the fact the IB powers the input stage allowing the inputs to go beyond the supply rail.  The datasheet has plots that have IB vs VCM and IB vs Vsense.  This give most of what you are looking for.  

    Regards,
