Parameter Ratings Supply Voltage 12.6 V Internal Power Dissipation1 SOIC Packages Observe power derating curves SOT-23 Package Observe power derating curves MSOP Package Observe power derating curves TSSOP Package Observe power derating curves Input Voltage (Common Mode) ±VS Differential Input Voltage ±2.5 V Output Short-Circuit Duration Observe power derating curves Storage Temperature Range (R) −65°C to +150°C Operating Temperature Range (A Grade) −40°C to +125°C Lead Temperature (Soldering 10 sec) 300°C 1 See Table 5. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. 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. THERMAL RESISTANCE Specification is for device in free air. Table 5. Thermal Resistance Package Type θJA Unit 8-Lead SOIC 125 °C/W 5-Lead SOT-23 180 °C/W 8-Lead MSOP 150 °C/W 14-Lead SOIC 90 °C/W 14-Lead TSSOP 120 °C/W MAXIMUM POWER DISSIPATION The maximum power that can be safely dissipated by the AD8051/AD8052/AD8054 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 can 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 AD8051/AD8052/AD8054 are internally short- circuit protected, this cannot 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.
