Hey guys, in a circuit im trying to establish a 12V, -12V voltage sources. I have an op-amp which requires it.
My teacher gave me a hint that if you had a regular 12V voltage supply it was possible in a way to use virtual grounds and voltage dividing with resistors and an op-amp to achieve this although I dont see exactly how. Hopefully you have some answers.
That puts a virtual ground half way between 0V and 12V, effectively splitting the world so you have -6V and +6V relative to the virtual ground, NOT -12V and +12V.
And because your teacher used power-wasting 100Ω resistors to create the voltage divider, he/she obviously lacks real world experience.
I was more questioning it the 12V was for another part of the circuit and not for the op-amp. But at first I need to consult with my teacher because im not sure if we have these kinds of op-amps.
Thanks for the help, I will post again if I have a question my teacher might have messed up
