LM4673 Class D Audio Power Amplifier

Texas Instruments LM4673 Class D Audio Power Amplifier is a single supply, high efficiency, 2.65W, mono, Class D audio amplifier. A low noise, filterless PWM architecture eliminates the output filter. This architecture reduces the external component count, board area consumption, system cost, and simplifies the design. The LM4673 is designed to meet the demands of mobile phones and other portable communication 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 supply requirements allow operation from 2.4V to 5.5V.
