Applic ations Information
Unipolar Output
Figure 6 shows the MAX5175/MAX5177 configured for
unipolar, rail-to-rail operation with a gain of +2V/V.
Table 2 lists the codes for unipolar output voltages. The
output voltage is limited to V
DD
.
Bipolar Output
Figure 7 shows the MAX5175/MAX5177 configured for
bipolar output operation. The output voltage is given by
the following equation (FB = OUT):
where N represents the numeric value of the DAC’s
binary input code and V
REF
is the voltage of the exter-
nal reference. Table 3 shows digital codes and the cor-
responding output voltage for Figure 7’s circuit.
Daisy-Chaining Devic es
The serial data output pin (DOUT) allows multiple
MAX5175/MAX5177s to be daisy-chained together as
shown in Figure 8. The advantage of this is that only
two lines are needed to control all of the DACs on the
line. The disadvantage is that it takes n commands to
program the DACs. Figure 9 shows several MAX5175/
MAX5177s sharing one common DIN signal line. In this
configuration the data bus is common to all devices;
however, more I/O lines are required because each
device needs a dedicated
CS
line. The advantage of
this configuration is that only one command is needed
to program any DAC.
