The following inputs are 3.3 V inputs but are 5 V tolerant: DDCA_SCL,
DDCA_SDA, DDCB_SCL, and DDCB_SDA.
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 ADV7612, the
user is advised to turn off the unused sections of the part.
Due to the printed circuit board (PCB) metal variation and,
therefore, 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 tempera-
ture using the measured package surface temperature and applies
only when no heat sink is used on the device under test (DUT):
where:
T
