    I am using AD9833 to generate sinewave. They have mentioned about digital supply(DVDD) and analog supply (VDD) to operate IC AD9833 . Both supplies operate at 5V.
    do i need to construct two powersupplies for the requirement?

    Possibly. Maybe not.

    What does the datasheet say?

    Does your usage correspond to the cases where they recommend separate power supplies?

    The spec sheet I looked at does not refer to separate power supplies, but does discuss the issues surrounding the digital and analogue grounds. Page 13 seems to outline the issues.
