How to power an opamp(with -5v) form USB?
I`m making a dac+amp with usb input and headphone out. I`m powering it from USB. The USB controller and the DAC uses 5v and 3.3V, but the opamp(LM4562) uses +-5v. How could I get this differential voltage form the 5V of the USB, even if i get less current.
If you can give me a good IC, it would be great, but if you can give me even a schematic (+IC) would be awesome.
