Stresses above those listed under Absolute Maximum Ratings

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.

MAXIMUM POWER DISSIPATION
The maximum safe power dissipation for the ADA4896-2/
ADA4897-1/ADA4897-2 is limited by the associated rise in
junction temperature (TJ) on the die. At approximately 150C,
which is the glass transition temperature, the properties of the
plastic change. Even temporarily exceeding this temperature
limit may change the stresses that the package exerts on the
die, permanently shifting the parametric performance of the
temperature of 175C for an extended period of time can result
in changes in silicon devices, potentially causing degradation or
loss of functionality.
The power dissipated in the package (PD) is the sum of the
quiescent power dissipation and the power dissipated in the
the output.
The quiescent power dissipation is the voltage between the supply
pins (±VS) multiplied by the quiescent current (IS).
PD = Quiescent Power + (Total Drive Power Load Power)

RMS output voltages should be considered. If RL is referenced to
VS, as in single-supply operation, the total drive power is VS ×
IOUT. If the rms signal levels are indeterminate, consider the worst
case, when VOUT = VS/4 for RL to midsupply.

In single-supply operation with RL referenced to VS, worst case
is VOUT = VS/2.
Airflow increases heat dissipation, effectively reducing θJA.
Also, more metal directly in contact with the package leads
and exposed paddle from metal traces, through holes, ground,
and power planes reduces θJA.
Figure 3 shows the maximum safe power dissipation in the
package vs. the ambient temperature on a JEDEC standard
4-layer board. θJA values are approximations.
