OK, I have clicked on both of your links.

What is your problem? What do you want to do? What is your question? At what stage are you in solving it?

Wouldn't an easier solution be to use a pwm pin with an R/C filter. With a settling time of 20mS I can't see much use for this.

I still don't understand what he is trying to do. Create a voltage proportional to the duty cycle (e.g., low-pass filter approach) or control a current as with LED's and other things?
