High there. I was hoping someone may be able to help me out a little.
I need to power an op amp from a +9v battery. Regulating this voltage down to + 5v would be straight forward enough, But I need to be able to supply +/-5V to theop amp.
A little reading rings up something called a charge pump, however ive never heard of, or used one of the devices, would someone be able to please point me in the correct direction.
the op amp will be amplifying an input from 0.2v to about 2 volts for audio perposes. The output will be a small pair of in ear headphones so the power cunsumption will be minimal.
I have a full schematic from my circuit however im sure we all know what an op amp looks like.
Thanks very mutch in advance.
Phil.
