Features SPiKe Protection Minimal amount of external components necessary Quiet fade-in/out mute mode Standby-mode Non-Isolated 15-lead TO-220 package Wide supply range 20V - 66V Description The LM4765 is a stereo audio amplifier capable of delivering typically 30W per channel of continuous average output power into an 8 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 LM4765, 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.
