Figure 9. Unipolar Output Circuit
Figure 9 depicts the MAX5152/MAX5153 configured for
unity-gain, unipolar operation. Table 2 lists the unipolar
output codes. To increase dynamic range, specific
gain configurations can be used as shown in Figure 10.

The MAX5152/MAX5153 can be configured for a bipo-
lar output, as shown in Figure 11. The output voltage is
given by the equation:
where NB represents the numeric value of the DAC’s
binary input code. Table 3 shows digital codes and the
corresponding output voltage for Figure 11’s circuit.
