About AD9280 Power Supply

Hi,

My customers were trying to use the AD9280 and I got some questions.

 

#1 Is there a stipulation in the order of turning on the analog AVDD and digital DVDD by turning on power to the IC?

 

#2    When analog signals that are out of the reference voltage range are input when using in Top / Bottom mode, what

        is the digital value?(AVDD ... 5 V, reference voltage Top ... 4.5 V, Bottom ... 2.5 V)

 

Best Regards,

Yuya
