Hello everyone,

We are working with a circuit that implements a dual supply op amp with 5V as the positive rail and -5V as the negative rail. The circuit also needs a common ground. We have a power supply that only ranges from 0 to 12V. What is the best way for us to acquire the -5V that we desire?

We are using an LM7805 for the 5V, power supply is held at 12V for other uses.

Thanks,
Daniel
