The LM3876TF/NOPB is a high-performance power Audio Amplifier with mute, capable of delivering 56W of continuous average power to an 8R load with 0.1% THD+N from 20Hz to 20kHz. The performance of the LM3876, 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, under-voltage, overloads, including shorts to the supplies, thermal run-away and instantaneous temperature peaks. The audio amplifier maintains an excellent signal-to-noise ratio of greater than 95dB (minimum) with a typical low noise floor of 2.0µV. It exhibits extremely low THD+N values of 0.06% at the rated output into the rated load over the audio spectrum and provides excellent linearity with an IMD (SMPTE) typical rating of 0.004%.
● >=95dB Signal-to-noise ratio
● An input mute function
● Output protection from a short to ground or to the supplies via internal current limiting circuitry
● Output overvoltage protection against transients from inductive loads
● Supply under-voltage protection, not allowing internal
●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
