www.ti.com LM4916 SNAS179E – MAY 2003 – REVISED MAY 2013 1.5V, Mono 85mW BTL Output, 14mW Stereo
Headphone Audio Amplifier
Check for Samples: LM4916 FEATURES 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 85mW into an
8Ω load at 1% THD+N. In Single Ended stereo
headphone mode, the amplifier delivers 14mW per
channel into a 16Ω load at 1% THD+N. 1 2 Single-Cell 0.9V to 2.5V Battery Operation
