1 / 34 page  LM4839 Stereo 2W Audio Power Amplifiers with DC Volume Control, Bass Boost, and Input Mux General Description The LM4839 is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifi- ers capable of producing 2W into 4 Ω (Note 1) with less than 1.0% THD+N, or 2.2W into 3 Ω (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 LM4839 incorporates a DC volume control, stereo bridged audio power amplifiers, selectable gain or bass boost, and an input mux making it optimally suited for multimedia monitors, portable radios, desktop, and portable computer applications. The LM4839 features an externally controlled, low-power consumption shutdown mode, and both a power amplifier and headphone mute for maximum system flexibility and performance. Note 1: When properly mounted to the circuit board, the LM4839LQ and LM4839MTE will deliver 2W into 4 Ω. The LM4839MT will deliver 1.1W into 8 Ω. See the Application Information section for LM4839LQ and LM4839MTE usage information. Note 2: An LM4839LQ and LM4839MTE that have been properly mounted to the circuit board and forced-air cooled will deliver 2.2W into 3 Ω.
