Part Number: AFE5812EVM
Hello TI people,
I have a question about the different ground in AFE5809/AFE5812 EVM.
It has three ground GND(Power GND), AGND and DGND(USB).
Now, From the schematic, I can see that Analog Ground is the Power ground. So would that be ok that if I connect AGND pins of an AFE5809/AFE5812 chip to normal ground and just keep two isolated ground on board, that will be GND and DGND.
In reply to Olu Sodipe:
That is true, it is mainly to prevent noise between analog and digital part.
On AFE5809EVM AnalogGND = Power GND so there is only two GND that I can see. Is it on purpose that EVM doesn't have it Analog GND separated? Because if we look in to AFE5809 datasheet there are pins for Analog GND.
