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 AD8276/AD8277

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.

SHORT-CIRCUIT CURRENT

The AD8276/AD8277 have built-in, short-circuit protection

that limits the output current (see Figure 25 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. Figure 3 and Figure 25, combined

with knowledge of the supply voltages and ambient temperature of

the part, can be used to determine whether a short circuit will

cause the part to exceed its maximum junction temperature.
