Adder using opamp741

[DhineshNDAS]

Hai, everybody... I am working with opamp741.. I just need to come up with an adder using this 741, But i have only positive supply... Can any one help me to design the adder using 741 with single power supplly...?

You need to be far less vague about what you're trying to do.

I guess he's talking about a summing amplifier.

Since he has only a positive supply then he doesn't know that any opamp works with one supply if its input is biased at half the supply voltage and coupling capacitors are used.
