LM4913 Overview
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.
