LM3886 is the latest high-power and high-performance integrated amplifier of NS company in the United States. It has good linearity in the range of 5HZ ~ 100KHZ, intermodulation distortion is as low as 0.004%, harmonic distortion and noise are only 0.03%, and there are overvoltage, undervoltage, and overvoltage. Stream, over temperature and other perfect protection functions and start-up shock mute function. This article introduces several practical applications of LM3886 in home theater systems.
1. High-quality dual-channel amplifier
The LM3886 outputs nearly 70W of continuous power at a rated voltage and a peak power of 150W. The two-channel power amplifier adopts simple and typical lines, which can replace a variety of low-end fever amplifiers, and is suitable for use as the left and right main channel amplifiers in home theaters. The whole circuit is installed on the same system board. Two LM3886 are equipped with a special aluminum material radiator with a length of 140 thick, 50 high and 75 (MM), which are fixed on both sides of the printed board to dissipate heat. The power transformer can choose dual 24 ~ 28V, 3 ~ 5A ring cattle.
2. Powerful BTL amplifier
