AD8132 ABSOLUTE MAXIMUM RATINGS Table 7.
The power dissipated in the package (PD) is the sum of the
Parameter Rating
quiescent power dissipation and the power dissipated in the Supply Voltage ±5.5 V package due to the load drive for all outputs. The quiescent VOCM ±VS power is the voltage between the supply pins (VS) times the Internal Power Dissipation 250 mW quiescent current (IS). The load current consists of the differential Operating Temperature Range −40°C to +125°C and common-mode currents flowing to the load, as well as Storage Temperature Range −65°C to +150°C currents flowing through the external feedback networks and Lead Temperature (Soldering 10 sec) 300°C the internal common-mode feedback loop. The internal resistor Junction Temperature 150°C tap used in the common-mode feedback loop places a 1 kΩ differential load on the output. Consider rms voltages and Stresses above those listed under Absolute Maximum Ratings currents when dealing with ac signals. may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any Airflow reduces θJA. In addition, more metal directly in contact other conditions above those indicated in the operational with the package leads from metal traces through holes, ground, section of this specification is not implied. Exposure to absolute and power planes reduces the θJA. maximum rating conditions for extended periods may affect device reliability.
