The LM4838 is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4? with less than 1.0% THD or 2.2W into 3? with less than 1.0% THD (see Notes below). Boomer audio integrated circuits were designed specifically to provide high quality audio while requiring a minimum amount of external components. The LM4838 incorporates a DC volume control, stereo bridged audio power amplifiers and a selectable gain or bass boost, making it optimally suited for multimedia monitors, portable radios, desktop, and portable computer applications.The LM4838 features an externally controlled, low-power consumption shutdown mode, and both a power amplifier and headphone mute for maximum system flexibility and performance.Note: When properly mounted to the circuit board, the LM4838NJB, LM4838PWP, and LM4838NYC will deliver 2W into 4?. The LM4838PW and LM4838YZR will deliver 1.1W into 8?.
