I have some question's about AD8212 for monitoring high voltage.
According to the datasheet, it says that "7 V to >500 V with external pass transistor ".
#1,Why is the common voltage limited upt to >500V ?
#2,Is it possible to use this device to monitor high voltage like 1500V?
If it's okay, what designer should consider?
And the datasheet example is using PNP transistor.
#3,Instead of PNP transistor,does the circuit work when Nch-IGBT like GT40WR21 is used?
Thanks in advance.
