I wonder how to configure the PIN1 of AD10200.
Hello. The Shield Pin (Pin 1) of the AD10200 is tied to the metal lid of the package. This pin is used to help improve the ground isolation between the A and B channel of the device and provide an opportunity for improved dynamic performance.
In applications where care is taken to isolate the analog grounding scheme of the A and B channels of the device, improved dynamic performance has been noted by experimenting with this pin and connecting it to the ground of either/or the A and B channel grounding scheme. So the pin can be left unconnected at the AD10200 or experimented with to see if additional dynamic performance can be achieved by connecting it to different Analog Ground points.
