80 Watt IC LM3875 Audio Amplifier

This Audio power Amplificator will deliver 80 watt of audio into an 8 Ohm load. The LM3875 IC devices should be suitably heatsinked. Note that the amplifier is a bridged circuit, with both speaker leads “hot”.

Note:
You should use supply Voltage about +/- 25Volt at do not lower 2-3A.

LM3875 Non-Inverting Gainclone Amplifier

That is, a single integrated circuit based on an operational amplifier (op amp) on a single substrate of silicon. The LM3875 is the ?weapon of choice?. This great chip, is a little larger than the size of a thumbnail and can deliver up to 56W RMS continuous with 100W peaks and it can do this at 0.05% distortion! Because they are DC amplifiers (DC coupling right through the amp) they can go all the way to 400kHz!

LM3875 Chip Amplifier

The Beast is a LM3875 Chip Amplifier, built from a popular chipamp kit. I’m hard to please and always looking for new things to try in audio. If it involves a DIY project, all the better. Mark and Gio had been after me to try a chipamp for some time. I really didn’t need any more amps and the spousal concern factor has been growing! My collection of gear exceeds size of my listening room and stray pieces are being stashed throughout the house. If you have looked at the other projects on the site you will see that a modified K-12 is my primary serious listening amp. It does what I ask and more.
