We need some evaluation board with AD9238 which is suitable for DC (not only
for AC). We know there are evaluation boards which allow only AC evaluation
(e.g. AD9238BCP-65EBZ ).
In contrast, other evaluation boards allow both DC and
AC evaluation (e.g. AD9238BST-40PCB)

Please explain whether AD9238BCP-65PCB allows DC evaluation or not


please find attached the schematic.

As you will see the Inputs are coupled by a balun (ADT1-1WT) and also AC
coupled via C14 and C13.

This prevents the system to react on DC.

Those systems in general work with AC Signals.
