General Description

The LM4808 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 using surface mount packaging. Since the LM4808 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.

The unity-gain stable LM4808 can be configured by external gain-setting resistors.

Features

  • LLP, MSOP, and SOP surface mount packaging
  • Switch on/off click suppression
  • Excellent power supply ripple rejection
  • Unity-gain stable
  • Minimum external components
