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 ADV7194 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 80-lead package is used for this device. The junction-to-
ambient (θ
is 24.7°C.
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
