Stresses at or above those listed under Absolute Maximum

Ratings may cause permanent damage to the product. This is a

stress rating only; functional operation of the product at these

or any other conditions above those indicated in the operational

section of this specification is not implied. Operation beyond

the maximum operating conditions for extended periods may

affect product reliability.

THERMAL RESISTANCE

θJA is specified for the worst-case conditions, that is, a device

soldered in a circuit board for surface-mount packages. The θJA

values in Table 3 assume a 4-layer JEDEC standard board with

zero airflow.

MAXIMUM POWER DISSIPATION

The maximum safe power dissipation for the AD8264 is limited

by the associated rise in junction temperature (TJ) on the die. At

approximately 150°C, 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 amplifiers. Exceeding a temperature of 150°C for an

extended period can cause changes in silicon devices, potentially

resulting in a loss of functionality.
