Thermal information

The power dissipated within the device depends primarly on the supply voltage, load

impedance and output modulation level. The PSSO36 Package of the STA518 includes an

exposed thermal slug on the top of the device to provide a direct thermal path from the IC to

the heatsink. For the Quad single ended application the Dissipated Power vs Ouptut Power

is shown in Figure 10.
