Default LM 3886 single ended output???

I posted this on class D amp forum and guess that was not the place to do it.

I need single ended output. Was told the lm 3886 was single ended. In reading through the information on lm3886 it seems they are running the normal power supplies and +/- power supplies. Also some kits and boards are running parallel chips to get more power.

If you run +/- power supply does it remain single ended output? And if you parallel chips can it remain single ended output?

Thanks Tom

A single-ended output is just an output where the signal is referenced to ground. Unlike a differential signal where the signal is the voltage difference between two signal pairs.

You are not saying that this is not an audio amplifier you need but something to drive a turntable motor.
Please upload what´s needed to drive them, motor data, similar schematics, etc.

If you need something to drive a motor, I suggest looking at pulse-width modulation. Use an H-bridge if you need to reverse direction.
