FEATURES  
DESCRIPTION  
The LM3886 is a high-performance audio power  
23  
•
68W Cont. Avg. Output Power into 4Ω at VCC  
±28V  
=
=
=
amplifier capable of delivering 68W of continuous  
average power to a 4Ω load and 38W into 8Ω with  
0.1% THD+N from 20Hz–20kHz.  
•
38W Cont. Avg. Output Power into 8Ω at VCC  
±28V  
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.  
•
•
50W Cont. Avg. Output Power into 8Ω at VCC  
±35V  
135W Instantaneous Peak Output Power  
Capability  
•
•
•
Signal-to-Noise Ratio ≥ 92dB  
An Input Mute Function  
Output Protection from a Short to Ground or  
to the Supplies via Internal Current Limiting  
Circuitry  
The LM3886 maintains an excellent signal-to-noise  
ratio of greater than 92dB with a typical low noise  
floor of 2.0µV. 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  
0.004%.  
•
•
Output Over-Voltage Protection against  
Transients from Inductive Loads  
Supply Under-Voltage Protection, not Allowing  
Internal Biasing to Occur when |VEE| + |VCC| ≤  
12V, thus Eliminating Turn-On and Turn-Off  
Transients

•
11-Lead TO-220 Package  
Wide Supply Range 20V - 94V  
APPLICATIONS

Component stereo  
Compact stereo  
Self-powered speakers  
Surround-sound amplifiers  
High-end stereo TVs
