These are stress ratings only, and functional operation of 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. (2) Measured with respect to GND. over operating free-air temperature range (unless otherwise noted) THERMAL CONDUCTIVITY 64ld QFN UNIT TJ Maximum Junction Temperature(1) 125 °C Theta junction-to-ambient (still air) 20 θ JA °C/W Theta junction-to-ambient (150 lfm) 16 θ JC Theta junction-to-case 7 °C/W θ JP Theta junction-to-pad 0.2 °C/W (1) Air flow or heat sinking reduces θ JA and may be required for sustained operation at 85° under maximum operating conditions. 4 Submit Documentation Feedback Copyright © 2007–2008, Texas Instruments Incorporated Product Folder Link(s): DAC5688 |
