DC electrical characteristics

The recommended operating conditions are listed in Table 22 and Table 23.

Thermal simulations should be done to verify if additional cooling is required. These

simulations should take into account power consumption, PCB dissipation, air flow and/or

heatsinks. The STreamPlug device can perform correctly above the specified ambient

temperature range if the maximum junction temperature remains below 125 °C.
