Audio Amp Headphone 2-CH Stereo 0.105W Class-AB 8-Pin LLP EP T/R, LM4809LQX/NOPB, Texas Instruments

The LM4809 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16? load with 0.1% (THD+N) from a 5V power supply.Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the LM4809 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.The unity-gain stable LM4809 can be configured by external gain-setting resistors. The LM4809 features an externally controlled, active-low, micropower consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.  

  • Active-Low Shutdown Mode
  • “Click and Pop” Reduction Circuitry
  • Low Shutdown Current
  • WSON, MSOP, and SOIC Surface Mount Packaging
  • No Bootstrap Capacitors Required
  • Unity-Gain Stable
  • THD+N at 1kHz at 105mW Continuous Average Power into 16? 0.1% (typ)
  • THD+N at 1kHz at 70mW Continuous Average Power into 32? 0.1% (typ)
  • Shutdown Current 0.4µA (typ)
