LM4854 1.9W Monaural / 85mW Stereo Headphone Audio Amplifier

The unity-gain stable LM4854 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 1.1W (typ) to an 8Ω load, 1.7W (typ) to a 4Ω load (Note 1) at 1% THD+N.

LM4854 Features

* a new circuit topology that suppresses output transients (’click and pops’) and eliminates SE-mode output coupling capacitors, saving both component and board space costs. The LM4854 has three inputs: one pair for a two-channel stereo signal and the third for a single-channel mono input. The LM4854
