/diy/ - Do It Yourself

So counts is the range divided by the resolution for that range. And the resolution for that range depends on the overall DAC resolution. How? How would you implement a 200mv range? If you have a fixed voltage reference of say 2v? Use a resistor divider after the Vref? And then how would you implement a 20v range? You'd then have to divide the input obviously, something like a 1:10 divider and Vref=2v. What happens with the resolution/counts in this case?
