LM4843MHX Features

  • Acoustically Enhanced DC Volume Control Taper
  • Stereo bridged power amplifiers
  • "Click and pop" suppression circuitry
  • Thermal shutdown protection circuitry

LM4843MHX Description

    The LM4843 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 or 2.2W into 3 with less than 1.0% THD.

    BoomerŪ audio integrated circuits were designed specifically to provide high quality audio while requiring a minimum amount of external components. The LM4843 incorporates a DC volume control with stereo bridged audio power amplifiers making it optimally suited for multimedia monitors, portable radios, desktop, and portable computer applications.

    The LM4843 features an externally controlled, low-power consumption shutdown mode, and both a power amplifier and headphone mute for maximum system flexibility and performance.
