Applic ations Information
Unipolar Output
Figure 6 shows the MAX5170/MAX5172 configured for
unipolar, rail-to-rail operation with a gain of +1.638V/V.
Table 2 lists the codes for unipolar output voltages. The
maximum output voltage is limited to V
DD
. Use the OS pin
to introduce an offset voltage as shown in Figure 7 and
described in the Offset and Buffer Configurations section.
Bipolar Output
Figure 8 shows the MAX5170/MAX5172 configured for
bipolar output operation. The output voltage is given by
the following equation (OS = AGND):
where N represents the numeric value of the DAC’s
binary input code, V
REF
is the voltage of the external
reference. Table 3 shows digital codes and the corre-
sponding output voltage for Figure 8’s circuit.
