    Check for Samples: LM4890 FEATURES DESCRIPTION The LM4890 is an audio power amplifier primarily
    designed for demanding applications in mobile
    phones and other portable communication device
    applications. It is capable of delivering 1 watt of
    continuous average power to an 8Ω BTL load with
    less than 1% distortion (THD+N) from a 5VDC power
    supply. 1 2 Available in Space-Saving Packages: DSBGA,
    VSSOP, SOIC, and WSON
    Ultra Low Current Shutdown Mode
    BTL Output Can Drive Capacitive Loads
    Improved Pop & Click Circuitry Eliminates
    Noises During Turn-On and Turn-Off
    Transitions
