Question
In order for an output to swing above and below a zero reference, the op-amp circuit requires-
The correct answer is
A negative and positive supply
If only a positive supply is used, the lowest theoretical output voltage is typically 0V (or slightly above), preventing the output from going into the negative voltage range. Therefore, to achieve an output swing that crosses the zero reference and goes into both positive and negative domains, the op-amp circuit requires a negative and positive supply.
