thanks you all, I'll manage it from here...
I was mistaken by saying I needed the 0 - 10 volts to send to pc, i am making an IO Board, that can be controlled by the PC, the analog output (0 - 10V) of the PIC will be used for controlling, what ever I want to make on that IO board...

Found info about a IO-Warrior24, that is quite similar to what I am making.

anyhow, I'll try the op-amp... that'll probably work
