1) Not subject to production test
2) Specified R_thJSP value is simulated at natural convection on a cold plate setup (all pins are fixed to ambient temperature).
T_a = 85 °C. Ch1 to Ch8 are dissipating 1 W power (0.125 W each).
3) Specified R_thJA value is according to Jedec JESD51-2,-3 at natural convection on FR4 1s0p board; The product
(Chip+Package) was simulated on a 76.2 x 114.3 x 1.5 mm board with minimal footprint copper area and 70 µm thickness.
T_a = 85 °C, Ch1 to Ch8 are dissipating 1 W power (0.125 W each).
4) Specified R_thJA value is according to Jedec JESD51-2,-3 at natural convection on FR4 1s0p board; The product
(Chip+Package) was simulated on a 76.2 x 114.3 x 1.5 mm board with additional heatspreading copper area of 300mm²
and 70 µm thickness. T_a = 85 °C, Ch1 to Ch8 are dissipating 1 W power (0.125 W each).
5) Specified R_thJA value is according to Jedec JESD51-2,-3 at natural convection on FR4 1s0p board; The product
(Chip+Package) was simulated on a 76.2 x 114.3 x 1.5 mm board with additional heatspreading copper area of 600mm²
and 70 µm thickness. T_a = 85 °C, Ch1 to Ch8 are dissipating 1 W power (0.125 W each).
6) Specified R_thJA value is according to Jedec JESD51-2,-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 70 µm Cu, 2 x 35 µm Cu).
T_a = 85 °C, Ch1 to Ch8 are dissipating 1 W power (0.125 W each).
