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.

MAXIMUM POWER DISSIPATION

The maximum safe power dissipation for the AD8273 is limited

approximately 150°C, which is the glass transition temperature,

the plastic changes its properties. 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 result in a loss of functionality.

The AD8273 has built-in, short-circuit protection that limits the

output current to approximately 100 mA (see Figure 2 for more

information). While the short-circuit condition itself does not

damage the part, the heat generated by the condition can cause

the part to exceed its maximum junction temperature, with

corresponding negative effects on reliability.
