100W LM3886 Parallel Stereo Power Amplifier

Hi, meet with me again now i try to share for 100W LM3886 Parallel Stereo Power Amplifier This amplifier is based on the PA100 line amplifier elaborate in Nationalist Semiconductor's coating tell - AN1192. Since my DIY speaker is 4-ohm and somewhat challenging to swing, I poorness to tally a much effectual amplifier to deal with it. Therefore I designed this amplifier which uses two LM3886 per water, in nonconvergent track.

This amp can present some 50W into a 8-ohm talker and 100W into a 4-ohm talker. This is a stereo amplifier and thence 4 LM3886s are old. The LM3886 circuit is in a non-inverted plan, so the signaling resistivity is settled by the input resistor R1, i.e. 47k. The 680 ohm and 470pF resistance capacitor strain cloth is misused to filter out the int {shot out the steep frequency noise at the LM3886 sign pins. I old upper grade frequence mark capacitors at individual locations: 1uF Auricap at the signaling for DC interference, 100uF Blackgate for C2 and C6, and 1000uF Blackgate at the render strain.for more information i fount the source for Circuit DIY 100W LM3886 Parallel Stereo Power Amplifier here
