dc generator

hello I desperately need a circuit that generates +100 or -100 mv can u give me any suggestions.
thanks
 

Re: dc generator

If the accuracy is not extremely critical, you can divide down a reference of your choice and buffer it with an opamp. You will have to adjust the circuit yourself, so the accuracy can only be as good as your meter, reference, etc.
I hope the current requirement is not high.
 

Re: dc generator

Suggestion of VVV is good. U can use a power opamp if you need more current.
Some power opamps are LM675, L465A, OPA547T/F.
