2) Specified R_thJA value is according to Jedec JESD51-2,-5,-7 at natural convection on FR4 2s2p board; The Product
(chip+package) was simulated on a 76.2 x 114.3 x 1.5 mm board with 2 inner copper layers (2 x 70µm Cu, 2 x 35µm Cu).
Where applicable a thermal via array under the exposed pad contacted the first inner copper layer.
