LM3886 High Performance Audio Power Amplifier IC

LM3886 High Performance Audio Power Amplifier IC

The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4? load and 38W into 8? with 0.1% THD N from 20Hz?20kHz. The performance of the LM3886, 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, under voltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks. The LM3886 maintains an excellent signal-to-noise ratio of greater than 92dB with a typical low noise floor of 2.0V.
