NOTES
1Absolute maximum ratings are limiting values, to be applied individually, and
beyond which the serviceability of the circuit may be impaired. Functional
operability under any of these conditions is not necessarily implied. Exposure to
absolute maximum rating conditions for extended periods of time may affect device
reliability.
2+VREF –VREF under all circumstances.
3Maximum junction temperature (tJ max) should not exceed +175°C for ceramic
packages, and +150°C for plastic packages:
tJ = PD (θJA) + tA
PD (θJC) + tC
where
PD = power dissipation
θJA = thermal impedance from junction to ambient (°C/W)
θJC = thermal impedance from junction to case ( °C/W)
tA = ambient temperature (°C)
tC = case temperature (°C)
Typical thermal impedances are:
Ceramic DIP θJA = 56°C/W; θJC = 20°C/W
Ceramic LCC θJA = 69°C/W; θJC = 23°C/W
PLCC θJA = 60°C/W; θJC = 19°C/W.

EXPLANATION OF TEST LEVELS
Test Level I – 100% production tested.
Test Level II – 100% production tested at +25°C, and
sample tested at specified temperatures.
Test Level III – Sample tested only.
Test Level IV – Parameter is guaranteed by design and
characterization testing.
Test Level V – Parameter is a typical value only.
Test Level VI – All devices are 100% production tested at
+25°C. 100% production tested at tempera-
ture extremes for extended temperature
devices; sample tested at temperature ex-
tremes for commercial/industrial devices.

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 AD9002 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.
WARNING!
