We are evaluating the ADuM4223.
Let me ask you some questions.
① Is the output a CMOS structure?
I am concerned about a short circuit in the power line of the internal structure.
(2) It is written in the data sheet that the distance between the power supply pin and the bypass capacitor should be 5 mm or less.
I want to know what happens if I don't.
③ Is it OK to draw a pattern directly under the IC?
What kind of problem will occur if a pattern is drawn directly under the IC?
Thank you for your consideration.
