Description

The LM3876TF 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 Hz20 kHz.

The performance of the LM3876TF, utilizing its Self Peak In-stantaneous Temperature (˚Ke) (SPiKe™) Protection Cir-cuitry, puts it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Oper-ating Area (SOA). SPiKe Protection means that these partsare completely safeguarded at the output against overvolt-age, undervoltage, overloads, including shorts to the sup-plies, thermal runaway, and instantaneous temperaturepeaks.

The LM3876TF maintains an excellent Signal-to-Noise Ratio of greater than 95 dB(min) with a typical low noise floor of 2.0 µV. It exhibits extremely low (THD + N) values of 0.06% at the rated output into the rated load over the audio spec-trum, and provides excellent linearity with an IMD (SMPTE)typical rating of 0.004%.
