I'am designing an application employing 16 pcs. AD5410 current loop dac. In the post “Procedure for grounding in AD5410” the separation of analog and digital ground planes is described. As mentioned in Pin 11 the analog and digital ground plane is joined together in the chip, both analog and digital planes should be joined at Pin 11 with a short trace as possible.
When I use 16 pcs. of AD5410 on one PCB, I can also just maintain one single point where I join both gnd planes(to prevent ground loops), but I have 16 times Pin 11. Should the remaining 15 Pins correspond to Analog or Digital Ground?
