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.

DB7
Most Significant Data Bit (MSB).
2–7
DB6–DB1
Data Bits 1–6.
8
DB0
Least Significant Data Bit (LSB).
9–14, 25 NC
No Internal Connection.
15
SLEEP
Power-Down Control Input. Active
High. Contains active pull-down circuit,
thus may be left unterminated if not
used.
16
REFLO
Reference Ground when Internal 1.2 V
Reference Used. Connect to AVDD to
disable internal reference.
17
REFIO
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.
18
FS ADJ
Full-Scale Current Output Adjust.
19
COMP1
Bandwidth/Noise Reduction Node.
Add 0.1
F to AVDD for optimum
performance.
20
ACOM
Analog Common.
21
IOUTB
Complementary DAC Current Output.
Full-scale current when all data bits
are 0s.
22
IOUTA
DAC Current Output. Full-scale
current when all data bits are 1s.
23
COMP2
Internal Bias Node for Switch Driver
Circuitry. Decouple to ACOM with
0.1
F capacitor.
24
AVDD
Analog Supply Voltage (+2.7 V to
+5.5 V).
26
DCOM
Digital Common.
27
DVDD
Digital Supply Voltage (+2.7 V to
+5.5 V).
28
CLOCK
Clock Input. Data latched on positive
edge of clock.
