LM4913 - 2W Monaural/ 90mW Stereo Headphone Audio Amplifier

Description

The unity-gain stable LM4913 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 2W (typ) to a 4Ω load (Note 1) at 0.3% THD+N.

Features

  • circuitry that suppresses output transients ("clicks and pops"). The LM4913 is designed for notebook and other handheld portable.

LM4913 2W Monaural, 90mW Stereo Headphone Audio Amplifier December 2002 LM4913 2W Monaural, 90mW Stereo Headphone Audio Amplifier General Description The unity-gain stable LM4913 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 2W (typ) to a 4Ω load (Note 1) at 0.3% THD+N. In SE stereo mode, the amplifier will deliver 90mW to 32Ω loads. The LM4913 features circuitry that suppresses output transients ("clicks and pops"). The LM4913 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.
