LM3886 is a high-performance audio power amplifier capable of delivering 68W continuous average power to a 4ohm load and 38W into ohms with 0.1% (THD+N) from 20Hz to 20 KHz.
The performance of the LM3886, utilizing its Self Peak instantaneous temperature (‘KE)(SPIKe) 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.
The LM3886 maintains an excellent Signal-to-Noise Ratio of greater than 92 dB with a typical low noise floor of 2.0uV. It exhibits extremely low (THD+N) values of 0.03% at the rated output into the rated load over the audio spectrum, and provides excellent linearity with an IMD (SMPTE) typical rating of 0.04%
