What do you mean through Load and Excitation output current?
The datasheet noted Load output current is 11mA, Excitation output current is
50mA rms.

The total power supply current to be supplied for AD698 is 12mA + 11mA + 50mA.
is this right?
FYI, It is to be connected LVDT with max current 9mA.

Please kindly calculate for this case.


This is not 100% correct, as you are mixing units.  Without an LVDT connected
to the AD698, the DC current is 12mA, typical.  The DC current consumption of
the customer’s LVDT, could then be added to this value, to determine the
overall current consumption.
