Description	Filterless High Efficiency 3W Switching Audio Amplifier
Datasheet	LM4670_NationalSemiconductor.pdf

The LM4670 is a fully integrated single-supply high efficiency switching audio amplifier.

an innovative modulator that eliminates the LC output filter used with typical switching amplifiers. Eliminating the output filter reduces external component count, simplifies circuit design, and reduces board area. The LM4670 processes analog inputs with a deltasigma modulation technique that lowers output noise and THD when compared to conventional pulse width modulators. The LM4670 is designed to meet the demands of mobile phones and other portable communication devices. Operating on a single.
