This amplifier is based on the PA100 parallel amplifier detailed in National Semiconductor’s application note – AN1192.100W LM3886 Parallel Stereo Power Amplifier – [Link]
Since my DIY speaker is 4-ohm and somewhat difficult to drive, I want to have a more powerful amplifier to match with it. Therefore I designed this amplifier which uses two LM3886 per channel, in parallel circuit. This amp can deliver about 50W into a 8-ohm speaker and 100W into a 4-ohm speaker. This is a stereo amplifier and therefore 4 LM3886s are used.
