The LM4766 is a stereo audio amplifier capable of deliveringtypically 40W per channel of conTInuous average outputpower 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 SafeOperaTIng Area (SOA). SPiKe Protection means that theseparts 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 independentsmooth transition fade-in/out mute that minimizes outputpops. The IC’s extremely low noise floor at 2 µV and its ex-tremely low THD + N value of 0.06% at the rated powermake the LM4766 optimum for high-end stereo TVs or mini-component systems.
