    www.ti.com SNAS217A – MAY 2004 – REVISED APRIL 2013 LM4991 3W Audio Power Amplifier with Shutdown Mode
    Check for Samples: LM4991 FEATURES DESCRIPTION The LM4991 is a mono bridged audio power amplifier
    capable of delivering 3W of continuous average
    power into a 3Ω load with less than 10% THD when
    powered by a 5V power supply (see Note below). To
    conserve power in portable applications, the
    LM4991's micropower shutdown mode (ISD = 0.1ВµA,
    typ) is activated when VDD is applied to the
    SHUTDOWN pin. 1 2 Available in Space-Saving WSON and SOIC
    Packages
    Ultra Low Current Shutdown Mode
    Can Drive Capacitive Loads up to 500pF
    Improved Click and Pop Circuitry Reduces
    Noises During Turn-On and Turn-Off
