7W into 8Ω — what the output rating means for your design
The 7W per channel into 8Ω is the continuous output power at the specified supply voltage and load. That figure drives the speaker selection and the thermal budget: at 7W into 8Ω, expect the device to dissipate roughly 1.5W to 2W internally at typical efficiency, so the PCB copper area and airflow around the DSBGA package need to handle that heat. The mono output is a single-ended BTL (bridge-tied load) configuration — no output coupling capacitor needed, which saves board space and BOM cost.
