LM4809 Datasheet Document

LM4809 Datasheet Document. Boomer audio power amplifiers were designed specifically to into 32 0.1% (typ) 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.

Features:

  • Active-low shutdown mode
  • "Click and Pop" reduction circuitry
  • Low shutdown current
  • WSON, MSOP, and SOIC Surface Packaging
  • No bootstrap capacitors required
  • Unity-gain stable

Applications:

  • Headphone Amplifier
  • Personal Computers
  • Microphone Preamplifier
  • PDA's

KEY SPECIFICATIONS

  • THD+N at 1kHz at 105mW Continuous Average
    Power into 16Ω 0.1% (typ)
  • THD+N at 1kHz at 70mW Continuous Average
    Power into 32Ω 0.1% (typ)
  • Shutdown Current 0.4μA (typ)
