CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD9708 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum
ratings for extended periods may effect device reliability.

Description
Most Significant Data Bit (MSB).
Least Significant Data Bit (LSB).
No Internal Connection.
Power-Down Control Input. Active
High. Contains active pull-down circuit,
thus may be left unterminated if not
used.
Reference Ground when Internal 1.2 V
Reference Used. Connect to AVDD to
disable internal reference.
Reference Input/Output. Serves as
reference input when internal reference
disabled (i.e., Tie REFLO to AVDD).
Serves as 1.2 V reference output when
internal reference activated (i.e., Tie
REFLO to ACOM). Requires 0.1 F
capacitor to ACOM when internal
reference activated.
Full-Scale Current Output Adjust.
Bandwidth/Noise Reduction Node.
Add 0.1 F to AVDD for optimum
performance.
Analog Common.
Complementary DAC Current Output.
Full-scale current when all data bits
are 0s.
DAC Current Output. Full-scale
current when all data bits are 1s.
Internal Bias Node for Switch Driver
Circuitry. Decouple to ACOM with
0.1 F capacitor.
Analog Supply Voltage (+2.7 V to
+5.5 V).
Digital Common.
Digital Supply Voltage (+2.7 V to
+5.5 V).
Clock Input. Data latched on positive
edge of clock.
