    I'm trying to purchase a D/A converter for generating an analog sine wave
    ->~3Vpp voltage
    ->linear sweep from 200-3500Hz and constant(programmed by matlab)
    ->supply ref voltage for amplifier circuit(Not intended to supply driving power)

    I have absolutely no idea which company or which product I should
    start from to implement my specification.(I've never used A/D or
    D/A converter, nor have I used and digital I/Os so far...)

    Which company and which product should I look for?
    Any suggestions or examples would be extremely helpful.

    What accuracy/resolution do you need?
    How may digital samples will be used to generate each sine-wave cycle (in other words how smooth does the sine-wave need to be)?

    8bits or higher should do the job..!

    You can try Analog Devices AD558. It is 8-bit DAC, parallel interface, voltage output, 5V single supply and easy to use.

    You didn't answer my second question.

    I could answer that question but best to let the OP think about it himself.
