AD8116

–4–

REV. B

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 the AD8116 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 degradation or loss of functionality.

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the

AD8116 is limited by the associated rise in junction tempera-

ture. The maximum safe junction temperature for plastic

encapsulated devices is determined by the glass transition

temperature of the plastic, approximately 150

°C. Temporarily

exceeding this limit may cause a shift in parametric performance

due to a change in the stresses exerted on the die by the package.

Exceeding a junction temperature of 175

°C for an extended

period can result in device failure.

While the AD8116 is internally short circuit protected, this may

not be sufficient to guarantee that the maximum junction temp-

erature (150

°C) is not exceeded under all conditions. To

ensure proper operation, it is necessary to observe the maximum

power derating curves shown in Figure 3.
