The power dissipated in the package (PD) for a sine wave and a

resistor load is the total power consumed from the supply Supply Voltage 12.6 V minus the load power. Power Dissipation See Figure 3 P Common-Mode Input Voltage −V D = Total Power Consumed − Load Power S + 1 V to +VS − 1 V Differential Input Voltage ±V 2 S V P = V × I – D ( SUPPLYVOLTAGE SUPPLYCURRENT) OUT Storage Temperature Range −65°C to +125°C RL Operating Temperature Range −40°C to +105°C Lead Temperature JEDEC J-STD-20 RMS output voltages should be considered. Junction Temperature 150°C Airflow across the ADA4860-1 helps remove heat from the Stresses above those listed under Absolute Maximum Ratings package, effectively reducing θJA. In addition, more metal may cause permanent damage to the device. This is a stress directly in contact with the package leads and through holes rating only; functional operation of the device at these or any under the device reduces θJA. other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute Figure 3 shows the maximum safe power dissipation in the maximum rating conditions for extended periods may affect package vs. the ambient temperature for the 6-lead SOT-23 device reliability.

Exceeding a junction temperature of 150°C for an extended period can result in changes in silicon devices, potentially causing degradation or loss of functionality.
ESD 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 this product 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.
