AD9748: Which pin is REFLO? It is mentioned in figure 16,17 and 18, but it can
not be found in pin description.

 

There is no REFLO pin on the AD9748. The AD9748 is the 8 bit member of the
family which includes the 14 bit AD9744. The AD9744, in addition to being
offered in the LFCSP package, is also offered in a 28 pin SOIC and TSSOP
package. In this package, there is a REFLO pin. The REFLO Pin is connected to
AGND when using the internal reference. To disable the internal reference, as
is commonly done when using an external reference, REFLO should be tied to
AVDD. Please see the according datasheets
