LM3886 68W High-Performance Audio Amplifier – Datasheet

6,312 views

The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4Ω load and 38W into 8Ω with 0.1% (THD + N) from 20 Hz–20 kHz. 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, Undervoltage, overloads, including shorts to the supplies.
