Aux ADC value settling time

Hi,

 

I'm referring to discussion http://ez.analog.com/message/69629

 

I also try to get 5 input signals with 4 aux ADCs on the ADAU1701 by multiplexing one of them.

The question is how long must I wait  when switching from one external measurement point to another until the measured voltage on the aux ADC input has settled to the new value?

Is there a minimum time that the aux ADC input needs (with activated filter) before I get back the correct value?

 

Thanks

Christian
