LM4841

The LM4841 is a monolithic integrated circuit that provides DC volume control and stereo bridged audio power amplifiers 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 headphoneamplifier- 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.
