ADA4311-1 ABSOLUTE MAXIMUM RATINGS Maximum Power Dissipation Table 2.
The maximum safe power dissipation for the ADA4311-1 is
Parameter Rating
limited by the associated rise in junction temperature (TJ) on Supply Voltage 13.6 V the die. At approximately 150°C, which is the glass transition Power Dissipation (TJMAX − TA)/θJA temperature, the plastic changes its properties. Even temporarily Storage Temperature Range −65°C to +125°C exceeding this temperature limit can change the stresses that the Operating Temperature Range −40°C to +85°C package exerts on the die, permanently shifting the parametric Lead Temperature (Soldering 10 sec) 300°C performance of the amplifiers. Exceeding a junction temperature of Junction Temperature 150°C 150°C for an extended period can result in changes in silicon Stresses above those listed under Absolute Maximum Ratings devices, potentially causing degradation or loss of functionality. may cause permanent damage to the device. This is a stress rating Figure 3 shows the maximum safe power dissipation in only; functional operation of the device at these or any other the package vs. the ambient temperature for the 10-lead conditions above those indicated in the operational section of MINI_SO_EP (44°C/W) on a JEDEC standard 4-layer board. this specification is not implied. Exposure to absolute maximum θJA values are approximations. rating conditions for extended periods may affect device reliability.
