About the input voltage range of ADuM3190

Hi,

I'm using the ADuM3190, and find the input common-mode voltage range is only between 0.3 to 1.5V. The maximum voltage 1.5 V is about 3.5 V lower than the supply voltage (when VDD1=VDD2 = 5V). Why is it like this? What is the internal structure of the input of ADuM3190?
