Low Power Audio Amplifier


  • Wide operating supply voltage range (2.0V to 16V), allows telephone line powered applications
  • Low quiescent supply current (2.7 mA typ.) for battery powered applications
  • Chip disable input to power down the IC
  • Low power-down quiescent current (65µA typ.)
  • Drives a wide range of speaker loads (8.0Ω and up)
  • Output power exceeds 250 mW with 32Ω speaker
  • Low total harmonic distortion (0.5% typ.)
  • Gain adjustable from <0dB to >46dB for voice band
  • Requires few external components
  • Operating temperature: -20°C to 70°C
  • Maximum load resistance: 100Ω
  • Typical gain bandwidth product: 1.5MHz
  • Maximum output current: 250mA
  • Maximum quiescent current: 5mA @ 16V
  • Total harmonic distortion noise: 0.6% @ 32Ω/200mW, 0.5% @ 80Ω/20mW
  • Maximum input bias current: 0.2µA @ 6V
