Can a 741 opamp be used to generate a negative voltage? I need to get the ouput of a dynamic mic and generate a negative voltage. If the input of the dynamic mike is 1 volt I need it to be -1. Can this be done with the 741 opamp? Is this the same as an inverting amp?

hi,
As its an ac coupled amp, you can offset the opa input using a resistive potential divider.
example: if the supply to the 741 is say +12v, set the +Vin of the 741 using a pair of resistors, to +6v.
