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.

PACKAGE THERMAL PERFORMANCE
The 64-lead package is used for this device. The junction-to-
ambient (θ
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:
Junction Temperature = (V
