DESCRIPTION
The unity gain stable LM4916 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 1.5V supply, the mono BTL mode delivers 85m W into an 8Ω load at 1% THD+N. In Single Ended stereo headphone...
