Figure 7 shows a method of connecting several
MAX5352/MAX5353s. In this configuration, the clock
and the data bus are common to all devices, and sepa-
rate chip-select lines are used for each IC.
__________Applic ations Information
Unipolar Output
For a unipolar output, the output voltage and the refer-
ence input have the same polarity. Figure 8 shows the
MAX5352/MAX5353 unipolar output circuit, which is
also the typical operating circuit. Table 2 lists the unipo-
lar output codes.
Figure 9 illustrates a rail-to-rail output. This circuit
shows the MAX5352 with the output amplifier config-
ured with a closed-loop gain of +2 to provide a 0V to 5V
full-scale range when a 2.5V reference is used. When
the MAX5353 is used with a 1.25V reference, this circuit
provides a 0V to 2.5V full-scale range.
Bipolar Output
The MAX5352/MAX5353 output can be configured for
bipolar operation using Figure 10’s circuit according to
the following equation:
V
OUT
= V
REF
[(2NB / 4096) - 1]
where NB is the numeric value of the DAC’s binary input
code. Table 3 shows digital codes (offset binary) and
the corresponding output voltage for Figure 10’s circuit.
NOTE: ( ) are for sub-bit.
Using an AC Referenc e
In applications where the reference has AC-signal com-
ponents, the MAX5352/MAX5353 have multiplying
capability within the reference input range specifica-
tions. Figure 11 shows a technique for applying a sine-
wave signal to the reference input where the AC signal
is offset before being applied to REF. The reference
voltage must never be more negative than GND.
