LM4910 - Output Capacitor-less Stereo 35mW Headphone Amplifier

General Description

The LM4910 is an audio power amplifier primarily designed for headphone applications in portable device applications.

It is capable of delivering 35mW of continuous average power to a 32Ω load with less than 1% distortion (THD+N) from a 3.3VDC power supply.

Key Features

  • 1.
  • 2 Eliminates headphone amplifier output coupling capacitors.
  • Eliminates half-supply bypass capacitor.
  • Advanced pop & click circuitry eliminates noises during turn-on and turn-off.
  • Ultra-low current shutdown mode.
  • Unity-gain stable.
  • 2.2V - 5.5V operation.
  • Available in space-saving MSOP, LLP, and SOIC packages.
