Yes all chips from  AD7606 series (including AD7606B, AD7606C(-16,-18),
AD7605-4, AD7606 (-4,-8,-6), AD7607, AD7608, AD7609), as well as AD7616
have a VDrive pin, as well as a RefSelect + RefIn/RefOut pin that takes
an input voltage in case RefSelect is high, or outputs the internal
reference voltage if RefSelect is low.
