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 indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
PACKAGE THERMAL PERFORMANCE
To reduce power consumption when using the ADV7623, turn
off the unused sections of the part.
Due to printed circuit board (PCB) metal variation and, thus,
variation in PCB heat conductivity, the value of θ
JA
may differ
for various PCBs.
The most efficient measurement solution is obtained using the
package surface temperature to estimate the die temperature
because this eliminates the variance associated with the θ
JA
value.
The maximum junction temperature (T
J MAX
) of 125°C must not
be exceeded. The following equation calculates the junction
temperature using the measured package surface temperature
and applies only when no heat sink is used on the DUT:
