MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the

AD816 is limited by the associated rise in junction temperature.

The maximum safe junction temperature for the plastic encap-

sulated parts is determined by the glass transition temperature

of the plastic, about 150

°C. Exceeding this limit temporarily

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.

The AD816 has thermal shutdown protection, which guarantees

that the maximum junction temperature of the die remains below a

safe level. However, shorting the output to ground or either power

supply for an indeterminate period will result in device failure.

To ensure proper operation, it is important to observe the derat-

ing curves and refer to the section on power considerations.

It must also be noted that in high (noninverting) gain configura-

tions (with low values of gain resistor), a high level of input

overdrive can result in a large input error current, which may

result in a significant power dissipation in the input stage. This

power must be included when computing the junction tempera-

ture rise due to total internal power.

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 AD816 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.
