LM4664 Filterless High Efficiency 1.
1W Switching Audio Amplifier March 2004 LM4664 Filterless High Efficiency 1.
1W Switching Audio Amplifier General Description The LM4664 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 LM4664 processes analog inputs with a delta-sigma modulation technique that lowers output noise and THD when compared to conventional pulse width modulators.
The LM4664 is designed to meet the demands of mobile phones and oth...
