but which oscillator preferred: dual or single supply

    I know this has been discussed, but I haven't found a comment on whether a single supply op amp oscillator(relaxation type) will perform as well as dual supply.

    Any preference?

    Does it depend on the op amp itself?

    Any opamp and any oscillator circuit will work with a single polarity supply if the opamp's input is biased at half the supply voltage.

    The oscillator's output will be the same if the supply has a single polarity or has a dual polarity.
