Description
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.
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 is designed for PDA, cellular telephone, notebook, and other handheld portable.
