I am building a guitar effects pedal circuit, as part of this circuit I am using a LM358N op amp. Previously when I had created op amp circuits using multisim, I could place 2 batteries in, separated by a ground to give me a positive supply and a negative supply for the op amp. Shown in attached image.
Is it possible to give a positive and negative supply to an op amp by using a single power supply? Would there be a way of reversing the polarity? (I only ask about reversing polarity as I think I had seen a circuit which supposedly did this on the internet somewhere, but can't remember where)
I think I need the positive and negative supplies as I need the full audio signal, I wanted to be able to supply it from 1 battery however.
Hopefully someone can help me here.
