PACKAGE THERMAL PERFORMANCE
To reduce power consumption when using the part the user is
advised to turn off any unused ADCs.
It is imperative that the recommended scripts be used for the
following high current modes: SCART, 720p, 1080i, and all
RGB graphic standards. Using the recommended scripts ensures
correct thermal performance. These scripts are available from
a local FAE.
The junction temperature must always stay below the
maximum junction temperature (T
the following equation, calculate the junction temperature:
