Default positive and dual power from LM675

Hi,
I have a smps of +18V 3.5A and want to put it to good use. I have a Class D amp (TPA3121) needing a +18v supply. The amp needs balanced input, so I have a DRV134 and a buffer needing dual supply. +/-9v is not ideal but this can be used to test the circuit. Is there a way to provide +18v and +/-9v at the same time? I looked at LM675 datasheet. It seems that you can have +/-9v from +18v, but the GND will be lifted. How would I obtain another +18v? How are the grounds connected?
Cheers.
