LM4766

LM4766 Overture™ Audio Power Amplifier Series Dual 40W Audio Power Amplifier with Mute September 1998 LM4766 Overture™ Audio Power Amplifier Series Dual 40W Audio Power Amplifier with Mute General Description The LM4766 is a stereo audio amplifier capable of delivering typically 40W per channel of continuous average output power into an 8Ω load with less than 0.1% (THD + N). 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 are safeguarded at the output against overvoltage, undervoltage, overloads, including thermal runaway and instantaneous temperature peaks. Each amplifier within the LM4766 has an independent smooth transition fade-in/out mute that minimizes output pops. The IC’s extremely low noise floor at 2 µV and its extremely low THD + N value of 0.06% at the rated power make the LM4766 optimum for high-end stereo TVs or minicomponent systems.
