I have a question about ADA4922-1. Is the Exposed Paddle of ADA4922-1 connected to GND or just a copper plane?
The exposed paddle on ADA4922-1 is for more efficient heat dissipation of the device. You can solder it to a copper plane for proper heat transfer.
For best thermal transfer or enhanced heat dissipation, it is recommended to connect the exposed paddle to the PCB ground plane.
I hope this helps.
Thanks for your reply! Should the copper plane be GND?
