Help wiring up DAC0800
The fact that the DAC0800 specifies needing at least +/- 4.5V means that you will not be able to run this chip with a 6V source (at least not to spec). You can DC bias this part to &quot;fake&quot; a bipolar supply but you will need at least a 9V supply to have the headroom to swing.
If possible, try to stick to any of the manufacturer's reference designs as much as as you can (Figures 18 and on). These can be a good starting point for most designs.
