Hello,
My customer is designing their product with multiple ADS8557s.
There is a layout recommendation in Figure 47 of The ADS8557 datasheet(SBAS404D).
From this recommendation, digital GND and analog DNG and connected at one point under the device.
I think this is relatively common recommendation for ADCs.
The question is when using multiple ADCs on the board, analog and digital GND should be connected at one point under all the ADCs?
Regards,
Oba
