AD813 2.5 Maximum Power Dissipation TJ = +150 C
The maximum power that can be safely dissipated by the AD813 is limited by the associated rise in junction temperature. The maximum safe junction temperature for the plastic encap-

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

While the AD813 is internally short circuit protected, this may not be enough to guarantee that the maximum junction tem-

ensure proper operation, it is important to observe the derating

AMBIENT TEMPERATURE – C
It must also be noted that in (noninverting) gain configurations Figure 3. Maximum Power Dissipation vs. Ambient (with low values of gain resistor), a high level of input overdrive Temperature 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 temperature rise due to total internal power.
