Thanks BigDog. I will study those files carefully. So temporarily I will follow what was stated in the AN655:

Hi...
Thx for replying randell :smile:
I was thinking about using it as DAC (FvM has pointed that out) feed into voltage regulators feedback pin such as LM317, LM2576 and such. The reason I'm asking is that people, especially engineers, usually picks many rule of thumb along the way :smile...
