LMH0394 - VEE and DAP

Other Parts Discussed in Thread: LMH0394

Hello team,

I assume on LMH0394 the VEE and DAP are not connected internally, can you please confirm?

Our customer used only DAP for the main ground connection and left VEE unconnected/floating in their new design and having problems with several boards. I would assume VEE is the main ground pin of the device which must be connected to negative rail on the board.

Thanks and regards,

Hi Mizanur,
On LMH0394 we have down bound. This means the DAP is connected to die GND or VEE. Having said this, for device characterization, VEE was soldered to the GND plane(like DAP). Therefor as noted in the data sheet VEE should be connected to GND and not floating.
