    LM4766 SNAS031F – SEPTEMBER 1998 – REVISED MARCH 2013 LM4766 Overture™ Audio Power Amplifier Series
    Dual 40W Audio Power Amplifier with Mute
    Check for Samples: LM4766 FEATURES DESCRIPTION The LM4766 is a stereo audio amplifier capable of
    delivering typically 40W per channel with the nonisolated "NDL" package and 30W per channel with
    the isolated "NDB" package of continuous average
    output power into an 8Ω load with less than 0.1%
    (THD+N). 1 23 SPiKe Protection
    Minimal Amount of External Components
    Quiet Fade-In/Out Mute Mode
    Non-Isolated 15-Lead TO-220 Package
    Wide Supply Range 20V -78V APPLICATIONS High-End Stereo TVs
    Component Stereo
    Compact Stereo KEY SPECIFICATIONS THD+N at 1kHz at 2 x 30W Continuous
    Average Output Power Into 8Ω 0.1% (Max)
    THD+N at 1kHz at Continuous Average Output
    Power of 2 x 30W Into 8Ω 0.009% (Typ) The performance of the LM4766, utilizing its Self
    Peak Instantaneous Temperature (°Ke) (SPiKe)
    Protection Circuitry, places it in a class above
    discrete and hybrid amplifiers by providing an
    inherently, dynamically protected Safe Operating
    Area (SOA). SPiKe Protection means that these parts ...
