NOTES
1
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 listed in the operational sections
of this specification is not implied. Exposure to absolute maximum rating condi-
tions 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 64-lead package is used for this device. The junction-to-
ambient (
θ
JA
) thermal resistance in still air on a four-layer PCB
is 38
°
C/W.
To reduce power consumption when using this part the user
can run the part on a 3.3 V supply, turn off any unused DACs.
The user must at all times stay below the maximum junction
temperature of 110
°
C. The following equation shows how to
calculate this junction temperature:

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 ADV7190/ADV7191 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precau-
tions are recommended to avoid performance degradation or loss of functionality.
