Stereo 2w Amplifiers With Dc Volume Control, Transient Free Outputs, And Cap-less Headphone Drive - National Semiconductor

The LM4841 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) or 2.2W into 3 (Note 2) with less than 1.0% THD. The LM4841 uses advanced, latest generation circuitry to eliminate all traces of clicks and pops when the supply voltages is first applied. The Amplifier has a headphone- amplifier-select input pin that is used to Switch the Amplifiers from bridge to single-ended mode for driving Headphones A new circuit topology eliminates Headphone output coupling capacitors (patent pending). Boomer Audio integrated circuits are designed specifically to provide high quality Audio while requiring a minimum amount of external components. The LM4841 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 LM4841 features an externally controlled, low-power consumption shutdown mode (Shutdown Low), and both a power Amplifier and Headphone mute for maximum system flexibility and performance. Note 1: When properly mounted to the circuit board, LM4841MH and LM4841LQ will deliver 2W into 4. The LM4841MT will deliver 1.1W into 8. See the Application Information section for LM4841MH usage information. Note 2: An LM4841MH that has been properly mounted to the circuit board and forced-air cooled will deliver 2.2W into 3.
