NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause permanent
damage to the device. This is a stress rating only; functional operation of the device
at these or any other conditions above those listed in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
2
Analog output short circuit to any power supply or common can be of an indefinite
duration.

PACKAGE THERMAL PERFORMANCE
The 44-PQFP package used for this device takes advantage of
an ADI patented thermal coastline lead frame construction. This
maximizes heat transfer into the leads and reduces the package
thermal resistance.
The junction-to-ambient (θ
JA
) thermal resistance in still air on a
four-layer PCB is 35.5°C/W. The junction-to-case thermal resis-
tance (θ
JC
) is 13.75°C/W.

NOTES
1
DAC ON Double 75R refers to a condition where the DACs are terminated in
a double 75R load and low power mode is disabled.
2
DAC ON Low Power refers to a condition where the DACs are terminated in a
double 75R load and low power mode is enabled.
3
DAC ON Buffering refers to a condition where the DAC current is reduced to
5 mA and external buffers are used to drive the video load.

FIELD/VSYNC
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 ADV7170/ADV7171 feature proprietary ESD protection circuitry, permanent
damage may occur on devices subjected to high energy electrostatic discharges. Therefore, pr oper
ESD precautions are recommended to avoid performance degradation or loss of functionality.
