application note AN1593 for the ADHV4702

Category: Datasheet/Specs
Product Number: ADHV4702

I have a question regarding application note AN1593 for the ADHV4702.

Q1: VCC and VEE fluctuate constantly. DGND connection
Should I create and connect a VCC-VEE intermediate potential separately?

(With VEE, I am concerned that the maximum absolute rating is VEE to VCC-12V and the margin is 0.)
2: To what potential should EXPAD be connected?

Thank you.
