General Description  
The LM3886 is a high-performance audio power amplifier  
capable of delivering 68W of continuous average power to a  
4load and 38W into 8with 0.1% (THD + N) from  
20 Hz–20 kHz.  
n 135W instantaneous peak output power capability  
n Signal-to-Noise Ratio 92 dB  
n An input mute function  
n Output protection from a short to ground or to the  
supplies via internal current limiting circuitry  
n Output over-voltage protection against transients from  
inductive loads  
n Supply under-voltage protection, not allowing internal  
biasing to occur when |VEE| + |VCC| 12V, thus  
eliminating turn-on and turn-off transients  
n 11-lead TO-220 package  
The performance of the LM3886, 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 parts  
are completely safeguarded at the output against overvolt-  
age, undervoltage, overloads, including shorts to the sup-  
plies, 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 2.0 µV. 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 rat-  
ing of 0.004%.  
Applications  
n Component stereo  
n Compact stereo  
n Self-powered speakers  
n Surround-sound amplifiers  
n High-end stereo TVs
