__________Applications Information
Unipolar Output
For a unipolar output, the output voltages and the refer-
ence inputs have the same polarity. Figure 9 shows the
MAX525 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 MAX525 with the output amplifiers configured with a
closed-loop gain of +2 to provide 0V to 5V full-scale
range when a 2.5V reference is used.
Bipolar Output
The MAX525 outputs can be configured for bipolar
operation using Figure 11’s circuit.
VOUT = VREF [(2NB / 4096) - 1]
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.
