Part Details:

High-Performance LM3876 August 2000 Overture LM3876 OvertureTMAudio Power Amplifier SeriesHigh-Performance 56W Audio Power Amplifier w/Mute Audio General Description Features 56W The LM3876 is a high-performance audio power amplifier n 56W continuous average output power into 8 capable of delivering 56W of continuous average power to n 100W instantaneous peak output power capability an 8 load with 0.1% THD+N from 20Hz­20kHz. Audio n Signal-to-Noise Ratio 95 dB(min) Power The performance of the LM3876, utilizing its Self Peak In- n An input mute function stantaneous Temperature (°Ke) (SPiKeTM) protection cir- n Output protection from a short to ground or to the cuitry, puts it in a class above discrete and hybrid amplifiers supplies via internal current limiting circuitry by providing an inherently, dynamically protected Safe Op- n Output over-voltage protection against transients from Power erating Area (SOA). SPiKe protection means that these inductive loads Amplifier parts are completely safeguarded at the output against ov- n Supply under-voltage protection, not allowing internal ervoltage, undervoltage, overloads, including shorts to the biasing to occur when |V | + |V | 12V, thus EE CC supplies, thermal runaway, and instantaneous temperature eliminating turn-on and turn-off transients peaks. Amplifier n 11-lead TO-220 package The LM3876 maintains an excellent signal-to-noise ratio of n Wide supply range 20V - 94V greater than 95dB (min) with a typical low noise floor of Series 2.0µV. It exhibits extremely low THD+N values of 0.06% at Applications the rated output into the rated load over the audio spectrum,and provides excellent linearity with an IMD (SMPTE) typical n Component stereo rating of 0.004%. n Compact stereo w/Mute n Self-powered speakers n Surround-sound amplifiers
