LM4666 Filterless High Efficiency Stereo 1.2W Switching Audio Amplifier May 2004 LM4666 Filterless High Efficiency Stereo 1.2W Switching Audio Amplifier General Description The LM4666 is a fully integrated single-supply high efficiency switching audio amplifier. It Features an innovative modulator that eliminates the LC output filter used with typical switching amplifiers. Eliminating the output filter reduces parts count, simplifies circuit design, and reduces board area. The LM4666 processes analog inputs with a delta-sigma modulation technique that lowers output noise and THD when pared to conventional pulse width modulators. The LM4666 is designed to meet the demands of mobile...
