    Read the link mcgyvr provided above, that tells you...

    Edit: If you are referring to the pin on the DAC, the definition of the pins are in the datasheet:

    as always... Step #1 = Read datasheet ;)

    It is hard work and requires much beer.

    It will eventually come back and bite you, if you don't read datasheet;)

    hi,
    i connecte the dac 0800(8bits) with arduino uno but it does not work
    i make a digitale variable voltage(0 to 255) in the inpout of the dac, but it gives me anything in output.
    the circuit is in figure 1 in the datasheet.
    please help me.

    If you want any help you are going to need to provide more information..
    You need to provide complete schematic of exactly how you have it wired and your complete arduino code and how you "make a digitale variable voltage"

    Again, you must read the datasheet. How can you expect to use a piece of hardware you obviously know nothing about? Answer: read the datasheet.

    The datasheet tells you exactly what you need to do to interface with the device. Please do that (particularly around page 20) and come back after trying again with the insight offered from reading the manual....
