LM4809MMX/NOPB is a dual, single-ended headphone amplifier for 2.0 V to 5.5 V systems. At 5 V it is specified for 105 mW per channel into 16 Ω or 70 mW into 32 Ω at 0.1% THD+N.

Best for

  • Stereo headphone amplifiers
  • Portable 5 V or lower-voltage audio designs
  • Single-ended audio outputs

Avoid if

  • A bridge-tied load output is required
  • Output coupling capacitors cannot be used
  • The load is below the validated application range

Check before use

  • Confirm output power at actual supply voltage and load
  • Select input and output coupling capacitors for the required low-frequency response
  • Keep local supply and bypass capacitors close to the IC
