- Sunnyvale, Calif.-Dec. 23, 1997-Philips Semiconductors announced the first low-voltage, high-power, single-chip audio power amplifierto feature a fully integrated, push-button operated, digital volume control.
- As you use a single supply and capacitor coupling, it means that the peak output of your amplifier is about half of the power supply voltage. So, to get 8VRMS (11.3Vpeak) the power supply as to be at least 22.6V, in practice it probably would need to be more than that because the output transistors in the chip drop some voltage.

- This subject is hotly debated topic amongst chip amp builders. If you are new to chip amp building I suggest the following arrangement. About 10-100 uF after the bridge rectifier, and 1000 uF on each (power supply) pin of the chip amp. If your speakers are a difficult load, you will need much more capacitance than this.
