This is the 100 Watt power amplifier circuit based power amp chip LM3886. Single chip of LM3886 is able to generate power output up to 68W.
In this 100W power amplifier circuit, the two of LM3886 are paralled to gain more powerful amplifier output. This amplifier can deliver about 50W into a 8-ohm speaker and 100W into a 4-ohm speaker. To make a stereo amplifier, there are should be use 4 pieces of LM3886.
The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4O load and 38W into 😯 with 0.1% THD+N from 20Hz–20kHz. It can be used for general purpose application such as Component stereo, Compact stereo, Self-powered speakers, Surround-sound amplifiers, High-end stereo TVs etc.
