Regulator with positive input and negative output

I'm trying to find out the best option for a regulator with positive input and negative output.

I need to feed six operational amplifiers with V+=(max: 12V min: 7V) and V-=-(max: 12V min: -7V) and I only have a power supply of 12V@1A.

On the whole, the total power consumption is around 600mWatts.

I don't mind to use a dual-output (+12V..+7V and -12V..-7V), but I would like to make sure to choose the best option and I have also to take into account compliance with EMC.

What do you consider it's the best option?

Thank you so much. Best Regards.
