Depending on the voltage range you're converting, 16 bit DAC is  
excellent.  Assuming for a second it's dealing with a 10 volt range,  
which is relatively large.  16 bit = 65,535 divisions.  That's 6,500  
per volt, less than a milllvolt per increment.  Ok, those are steps,  
but at what point do you call something not OK?  in my book, 12 bit  
is good enough for most applications.
