LM4914 - 1W Monaural/ 85mW Stereo Headphone Audio Amplifier

Datasheet Summary

Description

The unity-gain stable LM4914 is both a mono differential output (for bridge-tied loads, or BTL) audio power amplifier and a single-ended (SE) stereo headphone amplifier.

Operating on a single 5V supply, the mono BTL mode delivers 1W into an 8Ω load.

Features

  • circuitry that suppresses output transients ("clicks and pops"). The LM4914 is designed for notebook and other handheld portable.

LM4914 1W Monaural, 85mW Stereo Headphone Audio Amplifier March 2003 LM4914 1W Monaural, 85mW Stereo Headphone Audio Amplifier General Description The unity-gain stable LM4914 is both a mono differential output (for bridge-tied loads, or BTL) audio power amplifier and a single-ended (SE) stereo headphone amplifier. Operating on a single 5V supply, the mono BTL mode delivers 1W into an 8Ω load. In SE stereo mode, the amplifier delivers 85mW to 32Ω loads. The LM4914 features circuitry that suppresses output transients ("clicks and pops"). The LM4914 is designed for notebook and other handheld portable applications. It delivers high quality output power from a surface-mount package and requires few external components. The LM4914 is pin and functionally compatible with the TPA0253.
