General Description

The LM4836 is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4 with less than 1.0% THD+N, or 2.2W into 3 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 LM4836 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.

The LM4836 features an externally controlled, low-power consumption shutdown mode, and both a power amplifier and headphone mute for maximum system flexibility and performance.

Features

  • PC98 and PC99 Compliant
  • DC Volume Control Interface
  • Input mux
  • System Beep Detect
  • Stereo switchable bridged/single-ended power amplifiers
  • Selectable internal/external gain and bass boost configurable
  • "Click and pop" suppression circuitry
  • Thermal shutdown protection circuitry
