is the voltage applied to the external REFIN pin when
the external reference is selected and is VDD/2 if the
internal reference is used.

Figure 26. DAC Transfer Function
Figure 27 shows a typical setup for the AD7302 when using its
internal reference. The internal reference is selected by tying the
REFIN pin to VDD. Internally in the reference section there is a
reference detect circuit that will select the internal VDD/2 based
on the voltage connected to the REFIN pin. If REFIN is within
a threshold voltage of a PMOS device (approximately 1 V) of
VDD the internal reference is selected. When the REFIN voltage
is more than 1 V below VDD, the externally applied voltage at
this pin is used as the reference for the DAC. The internal
reference on the AD7302 is VDD/2, the output current to voltage
converter within the AD7302 provides a gain of two. Thus the
output range of the DAC is from 0 V to VDD, based on Table I.

Figure 27. Typical Configuration Selecting the Internal
Reference
Figure 28 shows a typical setup for the AD7302 when using an
external reference. The reference range for the AD7302 is from
1 V to VDD/2 V. Higher values of reference can be incorporated,
but will saturate the output at both the top and bottom end of
the transfer function. There is a gain of two from input to output
on the AD7302. Suitable references for 5 V operation are the
AD780 and REF192. For 3 V operation a suitable external
reference would be the AD589 a 1.23 V bandgap reference.
