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 in the AD8091/AD8092

package is limited by the associated rise in junction temperature

the junction temperature. At 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 AD8091/AD8092.

Exceeding a junction temperature of 175°C for an extended

period of time can result in changes in the silicon devices,

potentially causing failure.

The junction temperature can be calculated as

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on

the human body and test equipment and can discharge without detection. Although this product features

proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy

electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degrada-

tion or loss of functionality.
