Can the AD8332 be used in DC coupled application?
It is technically possible to DC couple to AD8332, but it is not recomended. We recomend trying to use one of our DC coupled VGAs like the AD8336 or AD8337.
In order to DC couple the AD8332 one would need to match the DC common mode voltage levels at the input and output of both the LNA and the VGA. An excercise that is usually not worth the effort.
