Stereo 2w Audio Power Amplifiers With Dc Volume Control - National Semiconductor

The LM4843 is a monolithic integrated circuit that provides DC Volume Control and stereo bridged Audio power amplifi- ers capable of producing 2W into 4 (Note 1) with less than 1.0% THD or 2.2W into 3 (Note 2) with less than 1.0% THD. Boomer Audio integrated circuits were designed specifically to provide high quality Audio while requiring a minimum amount of external components. The LM4843 incorporates a DC Volume Control with stereo bridged Audio power amplifi- ers making it optimally suited for Multimedia monitors, por- table Radios desktop, and portable computer applications. The LM4843 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 LM4843MH will deliver 2W into 4. See the Application Information section for LM4843MH usage information. Note 2: LM4843MH that has been properly mounted to the circuit board and forced-air cooled will deliver 2.2W into 3. By National Semiconductor Corporation
