Applications Discussion
Notes:
1. 4 Watt power represents the peak of the audio level and cannot be sustained without correct package thermal considerations.
The average audio signal can be sustained by the RC5512 without extra thermal considerations.
2. To improve the thermal resistance of the PLCC 28 package, a heat sink can be used. One possible vendor is: AAVID,
P/N CLC12059501.
