General Description

The LM4839 is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4Ω (Note 1) with less than 1.0% THD+N, or 2.2W into 3Ω (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.
