Bipolar Configuration
The MAX5200–MAX5203 are designed for unipolar opera-
tion, but can be used in bipolar applications with an exter-
nal amplifier and resistors. Figure 5 shows the
MAX5200–MAX5203 configured for bipolar operation. The
op amp is set for unity gain. Table 1 lists the offset binary
code for this circuit. The output voltage range is ±V
REF
.
Layout Considerations
Digital and AC transient signals coupling to AGND can
create noise at the output. Connect AGND to the high-
est quality ground available. Use proper grounding
techniques, such as a multilayer board with a low-
inductance ground plane. Wire-wrapped boards and
sockets are not recommended. For optimum system
performance, use printed circuit (PC) boards with sep-
arate analog and digital ground planes. Connect the
two ground planes together at the low-impedance
power-supply source. Connect DGND and AGND pins
together at the IC. The best ground connection is
achieved by connecting the DAC’s DGND and AGND
together, and then connecting that point to the system
analog ground plane. If the DAC’s DGND is connected
to the system digital ground, digital noise can get
through the DAC’s analog portion.
