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)
