Thermal Characteristics
The AD14160/AD14160L is packaged in a 452-lead ceramic
ball grid array (CBGA). The package is optimized for thermal
conduction through the core (base of the package) down to the
mounting surface. The AD14160/AD14160L is specified for a
case temperature (T
CASE
). Design of the mounting surface and
attachment material should be such that T
CASE
is not exceeded.

Thermal Cross-Section
The data below, together with the detailed mechanical drawings
at the end of the data sheet, allows for constructing simple ther-
mal models for further analysis within targeted systems. The top
layer of the package, where the die are mounted, is a metal V
DD
layer. The approximate metal area coverage from the metal
planes and routing layers is estimated below.
