In a mixed-voltage application for the ADA4899, should the exposed paddle be connected to actual GND or to the negative supply voltage?
The EPAD of the ADA4899 should be connected to ground.
Thank you. I will have 3 power connections then : V+, V- and GND.
Glad to help Stuart.
Just a note: even though you have a dual supply (ex. +/-5V) there should always be a GND in order for the supplies to have a reference. Without GND, the supplies will not know its level (for the voltage) and its path (for the current).
Thanks for patronizing ADI products.
