These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Table 3-1. System Thermal Characteristics(1) Power Rating at 25°C Derating Factor Power Rating at 70°C Power Rating at 85°C 2.3 W 28.57 mW/°C 1 W 0.6 W (1) This data was taken using 2-oz. (0.071-mm thick) trace and copper pad that is soldered to a JEDEC high-K, standard 4-layer 3-in. × 3-in. (7.62-cm × 7.62-cm) PCB. 4 ELECTRICAL SPECIFICATIONS Copyright © 2009, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TLV320DAC3120 |
