full scale) and should not be exceeded. Connect an input signal
in the range of 500 mV p-p to the evaluation board via analog
input connector, J1.
The EVAL-AD7405FMCZ has analog and digital ground planes
physically isolated from one other. As such, power to the analog
supply rail is by default, supplied through the on-board
ADuM6000 isolated iCoupler® 5 kV, dc-to-dc converter. V
may optionally be supplied from external connector, J3, or high
voltage connector, J4. A 24 V supply connected to J4 is stepped
down to 5 V by means of the on-board
to-dc regulator. Consult Table 2 if supplying V
If using the evaluation board in default mode of operation,
ensure that the link options are in their default positions as
outlined in Table 2. Ensure all links are in the appropriate
position before connecting the evaluation board to the
SDP-CH1Z.
