MisterX: I found the page on virtual grounds very informative, especially for my project! Do you have a suggestion for a step-up that can convert 2-3V to 10V?
I'm working with audio, so balance is important. My best idea thus far has been to use 3 voltage regs: one to step up 3V to 5V, one to step up 5V to a slightly higher level, and one to invert the slightly higher voltage to -5V. Obviously that's not quite ideal either.
I'm designing a portable device running off of 2 AA batteries that requires positive both positive and negative 5v power at the same time. What is the best/cheapest way to achieve this?
