I have an ADS8686SEVM_PDK evaluation module. I wish to connect the ADS8686 to a microcontroller, so the PHI board will be removed, the microcontroller will communicate using the pins on J18, and +3.3V and GND from the microcontroller will be connected to pins 1 & 2 of T1. The datasheet says to remove R28 if an external DVDD is used, but is that necessary if nothing is connected to J17? The schematics suggest it doesn't have to be removed.
All the best,
