I am confused on how the specs of a DAC work together.
I am looking at this one: http://www.ti.com/lit/ds/symlink/dac7811.pdf for a project and am wondering how the sampling rate (5 MSPS), the serial clock rate (50 MHz) and the resolution (12bits) all work together.
Where I'm getting lost is how the resolution and the sampling frequency work together. If my fs is 5 MHz, does this mean that I have 12 bits to represent 5M worth of values? Or does each single sample in the 5 M samples have a possible value from -=2^12?
This particular DAC has a 16 bit register with the first 4 being control registers, so what exactly goes into the last 12? They're binary values, so how can that accurately represent a signal being sampled at 5 MSPS? I know that the clock can operate at a max of 50MHz, which is how fast the DAC can send packages back and forth from my micro-controller. Does this value have anything to do with sampling rate or resolution?
I've been all over google and wikipedia for this and have checked with other students who aren't quite sure either. Can anyone offer clarification?
Edit to add: here is the link to the Newark.com page for this part where it specified 5 MSPS http://www.newark.com/texas-instruments/dac7811idgsr/digital-to-analog-converter-dac/dp/85K0568
