AD7858, voltage on analog input while powered down

Hello,

According to the absolute maximum ratings, the analog input voltage must be in the range -0.3 V to AVDD + 0.3 V. Is a positive voltage on one of the analog inputs before the AD7858 is powered up likely to cause a problem? What is the input impedance of analog inputs when the device is powered down?

Thank you,

Leo
