*Stresses above those listed under Absolute Maximum Ratings may cause perma-
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

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.

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
