.. LM4673 Filterless, 2.65W, Mono, Class D Audio Power Amplifier December 2005 LM4673 Filterless, 2.65W, Mono, Class D Audio Power Amplifier General Description The LM4673 is a single supply, high efficiency, 2.65W, mono, Class D audio amplifier. A low noise, filterless PWM architecture eliminates the output filter, reducing external ponent count, board area consumption, system cost, and simplifying design. The LM4673 is designed to meet the demands of mobile phones and other portable munication devices. Operating on a single 5V supply, it is capable of driving a 4Ω speaker load at a continuous average output of 2.1W with less than 1% THD+N. Its flexible power...
