LM4808 Dual 105 mW Headphone Amplifier - LM4808

LM4808 (ACTIVE)

LM4808 Dual 105 mW Headphone Amplifier

 

Description

The LM4808 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16Ω 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

  • WSON, VSSOP, and SOIC Surface Mount Packaging
  • Switch On/Off Click Suppression
  • Excellent Power Supply Ripple Rejection
  • Unity-Gain Stable
  • Minimum External Components
