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 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. 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 ex- tremely low THD + N value of 0.06% at the rated power make the LM4766 optimum for high-end stereo TVs or mini- component systems.
