741 and a single supply
Greetings!
Hmmm... I'm not sure if I understand how yer applying this circuit to the opamp. However, if it works, then I think yer on the right track.
There is a way to "trick" the critter into thinkin' it has a dual supply, when it's just a single supply. Yer resistors are correct, but again, I don't know how yer connecting them in conjunction with yer 741.
I'd like to recommend the Engineer's Mini-Notebook (Radio Shack
part # 62-5011) and on page-16, it discusses the fool-proof way to use a single supply with a 741.
Since I can't see yer circuit, I can't give U a proper suggestion right now. But if U'd like, U can email me the schemo (bob4analog@yahoo.com) and I can look at it further.
Till then, I think U'll really enjoy the Engineer's Mini-Notebook I suggested. I've found it to be very helpful.
Cheerz,
Bob
