ADAU1961 power down

I'm currently designing an application which can disable its analog section but the digital domain remains powered.

 

Scrutinizing the data sheet's absolute maximum ratings and all other sections about powering the ADAU1961 lead me to the assumption that I can shut down the AVDD supply but leave the IOVDD pin powered at the same time.

 

Is that possible or do I have to gate IOVDD as well?

 

Thanks and regards
