Product Summary

The LM4835MT is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4W with less than 1.0% THD or 2.2W into 3W 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 LM4835MT 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 LM4835MT features an externally controlled, low-power consumption shutdown mode, and both a power amplifier and headphone mute for maximum system flexibility and performance. Applications include: Portable and Desktop Computers, Multimedia Monitors, Portable Radios, PDAs, and Portable TVs.
