guidance on 12 bit PWM output from arduino

ya, i can certainly use the D/A converter but can anyone plz tell me which type does it come in and its specific number if any?? Plz guide me also in the matter of giving input in some way to the board in a 0-10V range (i know it works on TTL logic levels). Plz provide me with the link to the D/A converter specifications.

Can you be a bit clearer about what you want? The PWM in the title is irreverent is it? I would have thought so.

Is this an analogue or digital value? Two resistors as a voltage divider should do, make them 1K each. http://en.wikipedia.org/wiki/Voltage_divider
