I'm working on a circuit with about 6 op-amps and need a dual supply. I was told I could use two +15V supplies to create both rails. The circuit that was given to me is attached... Your drawing has no errors or flaws, assuming each supply has isolated outputs with no connection to input ground or common.
I don't think I did anything wrong when I assembled it, however, it's remotely possible that I did err somewhere. It's not like it's that difficult to make, which is why I don't think I screwed up!
My problem is, I'm measuring +30V from the positive terminal to the common, and -15V from the negative to the common. Why am I measuring +30V?Not sure, but are those measurements being taken with anything being wired up to the output voltages?
What voltage do you read if measured between the +15 terminal and the -15 terminal without anything connected to the output terminals except your voltmeter ?
I, stupidly, heat-shrinked the cables and connection points so I haven't wanted to rip it open and ruin all of my work yet!Well you must be the very first person in all of history to do something like that, NOT!
Thanks for any advice!Just continue your troubleshooting adventure, there is always a logical explaination once it is all figured out. Electronics seldom operates in mysterious ways. Software however is a whole different ballgame.
