Parameter Rating Supply Voltage 13.6 V Power Dissipation (TJMAX − TA)/θJA Storage Temperature Range −65°C to +125°C Operating Temperature Range −40°C to +85°C Lead Temperature (Soldering 10 sec) 300°C Junction Temperature 150°C 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 Thermal resistance (θJA) is specified for the worst-case conditions, that is, θJA is specified for device soldered in circuit board for surface-mount packages. Table 3. Package Type θJA Unit 10-Lead MINI_SO_EP 44 °C/W Maximum Power Dissipation The maximum safe power dissipation for the ADA4311-1 is limited by the associated rise in junction temperature (TJ) on the die. At approximately 150°C, which is the glass transition temperature, the plastic changes its properties. Even temporarily exceeding this temperature limit can change the stresses that the package exerts on the die, permanently shifting the parametric performance of the amplifiers. 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. Figure 3 shows the maximum safe power dissipation in the package vs. the ambient temperature for the 10-lead MINI_SO_EP (44°C/W) on a JEDEC standard 4-layer board. θJA values are approximations.
