voltage on AD7478 Vin pin

I am using AD7478 to measure the battery voltage and its working fine.

Problem is whenever i remove the battery (i.e leave the Vin pin of ADC floating), i get a voltage on 5 volts on Vin pin.

Is this a normal behavior?

I cannot use pull-ups or pull-downs on this Vin pin, because it will consume battery energy.


Thanks & Regards,
