I'm an electronics dummy and I find it all a bit daunting, but I'm hoping to pick up a bit of knowledge along the way.
I've been looking at the Non inverting operational amplifier, and how I can use it to double a DC input voltage.
I have come up with the following circuit diagram
If V1 is between 0 & 2.5v and both resistors are equal, I think Vout should be between 0 & 5.0v, correct ?
Will it operate on varying voltage, or does it have to be fixed ?
How do I determine which Op amp I should use ?
Also, I have some 1 meg ohm resistors..... are they too large to use to provide my 'gain' ?
Sorry for the basic questions, and thanks for any input
