We plan to implement a voltage follower by using AD8000. The schematic design likes below
My questions are:
1. Is this implemented? Do I need to add feed back resistor between feedback pin and input port?
2. Can i need to connect output pin and feed back pin external?
3. Pin-9 is let floating, is this ok?
1. Feedback resistor is necessary;
2. Don't need.
3. It's better to connect to GND. Please read the datasheet "Exposed Paddle" part.
