The SRO output swings from V
to other MAX500s poses no problem. If SRO is used to
drive a TTL-compatible input, use a clamp diode
between TTL +5V and V
resistor to prevent potential latchup problems with
the 5V supply.
Table 2 shows the truth table for SDA, SCL, LOAD, and
LDAC operation. Figures 5 and 6 show the timing dia-
grams for the MAX500.
The MAX500 is fully specified to operate with V
between +12V ±5% and +15V ±10% (+11.4V to
+16.5V), and with V
mance is also guaranteed for single-supply operation

The MAX500 is specified to operate with a reference
input range of +2V to V
Digital or AC transient signals between AGND and
DGND will create noise at the analog outputs. It is rec-
ommended that AGND and DGND be tied together at
the DAC and that this point be tied to the highest quali-
ty ground available. If separate ground buses are used,
then two clamp diodes (1N914 or equivalent) should be
connected between AGND and DGND to keep the two

avoid parasitic device turn-on, AGND must not be
allowed to be more negative than DGND. DGND should
be used as supply ground for bypassing purposes.
