Package thermal characteristics
Using a double-layer PCB the thermal resistance, junction to ambient, with 2 copper ground
areas of 3 x 3 cm
The dissipated power within the device depends primarily on the supply voltage, load
impedance and output modulation level.
Thus, the maximum estimated dissipated power for the STA333BW is:
