I have a simple question about power supplies for op amps. The only place I ever used them was in lab at university. They didn't really explain why op amps have + 15V and -15V for example except that it means the output can go as high as +15 and as low as -15.
In lab we have power supplies that have a positive and negative terminal as well as ground. We always used all 3 terminals for op amp circuits.
So now I want to hook up an op amp at home, and all I have is a power supply that can go between ground and +15V. I want to amplify a sine wave from the new function generator kit that I just put together in order to test the function generator.
If I connect Vcc to +12V and Vee to ground on a 741 op amp, will that mean that only the positive half of my sine wave will be amplified and the negative part cut off?
If that is true, how do I fix that if all I have is the power supply with +15V and ground terminals?
Thanks
