microcontroller I/O pins required. During power-down,
this output will retain its digital state prior to shutdown.
When
CLR
is pulled low, UPO will reset to its program-
med default state. See Table 1 for specific commands
to control the UPO.
Reset (RS ) and Clear (
CLR
)
The MAX5171/MAX5173 offers a clear pin which resets
the output voltage. If RST = DGND, then
CLR
resets the
output voltage to the minimum voltage (0 if no offset is
introduced). If RST = V
DD
, then
CLR
resets the output
voltage to midscale. In either case,
CLR
resets UPO to
its programmed default state.
___________Applic ations Information
Unipolar Output
Figure 6 shows the MAX5171/MAX5173 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 MAX5171/MAX5173 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 VREF is the voltage of the exter-
nal reference. Table 3 shows digital codes and the cor-
responding output voltage for Figure 7’s circuit.
