ADG824 / ADG884 switch impedances with Vdd=0

Hi,

We are considering using either the ADG824 or the ADG884 dual SPDT analog switches, however our application requires the switch analog terminals to be in a high-Z state with the device Vdd=0 V as audio signals are still likely to be present even with Vdd=0.

I cannot find this information in the datasheet, so I would like to know if this is the case or not ? Are the switches in High-Z states when no power is applied to the device Vdd ?

Looking forward to your reply.

Regards, Mike
