LINK CONFIGURATION OPTIONS
Multiple link options must be set correctly to select the appropriate
operating setup before using the EVAL-AD7386FMCZ. The
functions of these options are detailed in Table 2.
Setup Conditions
Ensure that all link positions are set as required by the selected
operating mode before applying power and signals to the
evaluation boards. Table 2 shows the default positions of the
links when the EVAL-AD7386FMCZ is packaged.

Position refers to the pin on the link. For example, Positon 3-4 means Pin 3 and Pin 4 of the link is shorted by a header stub, and the SMD resistor is the surface-mount
device resistor.
