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. (2) All voltage values are with respect to GND. (3) Do not apply voltage to these pins. PACKAGE θ JA θ JA θ JA LOW K, °C/W HIGH K, °C/W BEST(2), °C/W DDA 190(3) 45(4) 45 (1) Tested per JEDEC JESD51, natural convection. The definitions of high-k and low-k are per JESD 51-7 and JESD 51-3. (2) The best case thermal resistance is obtained using the recommendations per SLMA002A (2 signal – 2 plane with the pad connected to the plane). (3) Low-k (2 signal – no plane, 3 in. by 3 in. board, 0.062 in. thick, 1 oz. copper) test board with the pad soldered, and an additional 0.12 in.2 of top-side copper added to the pad. (4) High-k is a (2 signal – 2 plane) test board with the pad soldered.
