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). 324-lead plastic TSSOP; θ JA = 128°C/W. Maximum internal power dissipation (P D) should be derated for ambient temperature (TA) such that PD < (150°C–TA)/θJA. ORDERING GUIDE Temperature Package Package Model Range Description Option AD8183ARU –40 °C to +85°C 24-Lead Plastic TSSOP RU-24 AD8185ARU –40 °C to +85°C 24-Lead Plastic TSSOP RU-24 AD8183-EVAL Evaluation Board AD8185-EVAL Evaluation Board MAXIMUM POWER DISSIPATION The maximum power that can be safely dissipated by the AD8183/ AD8185 is limited by the associated rise in junction temperature. 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 AD8183/AD8185 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 2. 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 AD8183/AD8185 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. WARNING!
