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.
The max estimated dissipated power for the STA333ML is:
2 x 20 W into 8 Ω, at 18 V
