1 / 16 page ![]() LM1876 Overture™ Audio Power Amplifier Series Dual 20W Audio Power Amplifier with Mute and Standby Modes General Description The LM1876 is a stereo audio amplifier capable of delivering typically 20W per channel of continuous average output power into a 4 Ω or 8Ω load with less than 0.1% (THD + N). Each amplifier has an independent smooth transition fade-in/ out mute and a power conserving standby mode which can be controlled by external logic. The performance of the LM1876, utilizing its Self Peak In- stantaneous Temperature (˚Ke) (SPiKe™) Protection Cir- cuitry, places it in a class above discrete and hybrid amplifi- ers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPiKe Protection means that these parts are safeguarded at the output against overvoltage, un- dervoltage, overloads, including thermal runaway and in- stantaneous temperature peaks.
