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
precautions are recommended to avoid performance degradation or loss of functionality.

PACKAGE THERMAL PERFORMANCE
The 64-lead package is used for this device. The junction-to-
ambient (q
is 38∞C/W.
To reduce power consumption when using this part, the user can
run the part on a 3.3 V supply, and 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:
Junction Temperature = (V
