MAXIMUM POWER DISSIPATION
The maximum safe power dissipation in the ADA4932-x
package is limited by the associated rise in junction temperature
(T
transition temperature, the plastic changes its properties. Even
temporarily exceeding this temperature limit can change the
stresses that the package exerts on the die, permanently shifting
the parametric performance of the ADA4932-x. Exceeding a
junction temperature of 150°C for an extended period can result
in changes in the silicon devices, potentially causing failure.

quiescent power dissipation and the power dissipated in the
package due to the load drive. The quiescent power is the voltage
between the supply pins (V
The power dissipated due to the load drive depends upon the
particular application. The power due to load drive is calculated
by multiplying the load current by the associated voltage drop
across the device. RMS voltages and currents must be used in
these calculations.
Airflow increases heat dissipation, effectively reducing θ
addition, more metal directly in contact with the package leads/
exposed pad from metal traces, through holes, ground, and power
planes reduces θ
Figure 4 shows the maximum safe power dissipation in the
package vs. the ambient temperature for the single 16-lead
LFCSP (91°C/W) and the dual 24-lead LFCSP (65°C/W) on a
JEDEC standard 4-layer board with the exposed pad soldered to
a PCB pad that is connected to a solid plane.
