LM4913 Datasheet (National Semiconductor) - 2W Monaural/ 90mW Stereo Headphone Audio Amplifier

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

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 a

* 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. The LM4913 is pin and functionally compatible with t
