__________Applic ations Information
Unipolar Output
For a unipolar output, the output voltages and the refer-
ence inputs have the same polarity. Figure 9 shows the
MAX5253 unipolar output circuit, which is also the typi-
cal operating circuit. Table 2 lists the unipolar output
codes.
For rail-to-rail outputs, see Figure 10. This circuit shows
the MAX5253 with the output amplifiers configured with
a closed-loop gain of +2.6 to provide 0V to 3.25V full-
scale range when a 1.25V reference is used.
Table 2. Unipolar Code Table
Bipolar Output
The MAX5253 outputs can be configured for bipolar
operation using Figure 11’s circuit.

where NB is the numeric value of the DAC’s binary
input code. Table 3 shows digital codes (offset binary)
and corresponding output voltages for Figure 11’s
circuit.
