The LM3875 is a high-performance audio power amplifier capable of delivering 56W of continuous average power to an 8Ω load with 0.1% (THD + N) from 20 Hz–20 kHz. The performance of the LM3875, utilizing its Self Peak Instantaneous Temperature Protection Circuitry, puts 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 completely safeguarded at the output against overvoltage, Undervoltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks.
