[SOLVED] How to generate 16-bit binary values?

I'm not sure what you mean... do you need to generate random values? And what's the DAC meant to be used for?
 

Maybe. I don't know. Somebody on the net asked that he/she wants 50V from a dac circuit and the o/p of dac will be 4.7V. See attached file. I have done something like this.

Assuming this will be the real circuit you'll be using, you should put a protection resistor up of RV3 to limit the maximum reference voltage value (when I put RV3 full up the voltage on the display continues rising without stopping, getting over 50V).
Anyway, if your purpose was to get sequential numbers (of whatever size), I guess a simple loop would do the trick. Or did we miss something in the middle? Anyway, I'm glad you found a solution
