Part Details:

Dual LM4766 March 2006 40W Overture LM4766 OvertureTM Audio Audio Power Amplifier Series Dual 40W Audio PowerAmplifier with Mute Power TM General Description Key Specifications Audio The LM4766 is a stereo audio amplifier capable of delivering j THD+N at 1kHz at 2 x 30W continuous typically 40W per channel with the non-isolated "T" package average output power into 8 0.1% (max) and 30W per channel with the isolated "TF" package of Amplifier continuous average output power into an 8 load with less j THD+N at 1kHz at continuous average than 0.1% (THD+N). output power of 2 x 30W into 8 0.009% (typ) Power The performance of the LM4766, utilizing its Self Peak In-stantaneous Temperature (°Ke) (SPiKeTM) Protection Cir- Features cuitry, places it in a class above discrete and hybrid amplifi-ers by providing an inherently, dynamically protected Safe n SPiKe Protection with Amplifier Operating Area (SOA). SPiKe Protection means that these n Minimal amount of external components necessary parts are safeguarded at the output against overvoltage, n Quiet fade-in/out mute mode undervoltage, overloads, including thermal runaway and in- n Non-Isolated 15-lead TO-220 package stantaneous temperature peaks. Mute n Wide Supply Range 20V - 78V Each amplifier within the LM4766 has an independentsmooth transition fade-in/out mute that minimizes output Applications pops. The IC s extremely low noise floor at 2µV and its Series extremely low THD+N value of 0.06% at the rated power n High-end stereo TVs make the LM4766 optimum for high-end stereo TVs or mini- n Component stereo component systems. n Compact stereo Connection Diagram Plastic Package 10092802 Top View
