Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

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.

THERMAL RESISTANCE

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 AD8476 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 may result in a loss of functionality.
