Can't get the ADUM32220 to work

The input signal is set to 3V but the output is always 0V on both channels

 

See schematic below:

 

VDD1 = 3.3V

VDD2 = 15V

Vin logic = 3.3V

For this tests PGND and IGND are all connected

 

Can this device support DC level inputs?

 

Any suggestions will be appreciated

 

Thank you
