Unipolar Output
Figure 7 shows the MAX5510 in a unipolar output con-
figuration with unity gain. Table 4 lists the unipolar out-
put codes.
Bipolar Output
The MAX5510 output can be configured for bipolar
operation, as shown in Figure 8. The output voltage is
given by the following equation:
V
OUT
= V
REF
x [(N
A
- 128) / 128]
where NA represents the numeric value of the DAC’s
binary input code. Table 5 shows digital codes (offset
binary) and the corresponding output voltage for the
circuit in Figure 4.
Configurable Output Gain
The MAX5510/MAX5511 have a force-sense output,
which provides a connection directly to the inverting ter-
minal of the output op amp, yielding the most flexibility.
The advantage of the force-sense output is that specific
gains can be set externally for a given application. The
gain error for the MAX5510/MAX5511 is specified in a
unity-gain configuration (op-amp output and inverting ter-
minals connected), and additional gain error results from
external resistor tolerances. Another advantage of the
force-sense DAC is that it allows many useful circuits to
be created with only a few simple external components.
