Description

The LM4849 is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4Ω (Note 1) with less than 1.0% THD+N, or 2.2W into 3Ω (Note 2) with less than 1.0% THD+N. 

Boomer® audio integrated circuits were designed specifically to provide high quality audio while requiring a minimum amount of external components. The LM4849 incorporates a DC volume control, stereo bridged audio power amplifiers, and an input mux making it optimally suited for multimedia monitors, portable radios, desktop, and portable computer applications. 

The LM4849 features an externally controlled, low-power consumption shutdown mode, and both a power amplifier and headphone mute for maximum system flexibility and performance.
