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. 2Specification is for device in free air (T A = 25 °C). 316-lead plastic TSSOP; θ JA = 150.4 °C/W. Maximum internal power dissipa- tion (PD) should be derated for ambient temperature (T A) such that PD < (150 °C – T A)/ θ JA.

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 junc- tion temperature of 175 °C for an extended period can result in device failure. While the AD8074/AD8075 is internally short circuit protected, this may not be sufficient to guarantee that the maximum junction temperature (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 1. WARNING! ESD SENSITIVE DEVICE 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 AD8074/AD8075 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. AMBIENT TEMPERATURE – C TJ = 150 C 010 30 50 70 90 0 0.5 1.0 1.5 –50 –30 –10 Figure 1.
