What is the MCP3208 DAC option?

I see in the MCP3208.spin file that it offers a DAC, but I don't know where this is coming from or how to use it. Can anybody shed some light on this?

    Nothing to do with the MCP3208 itself but more to do with the fact that since you need to dedicate a cog (in Spin) to talk to the chip then it would seem a waste if the cog's two counters couldn't be used as DACs using the RC filter method, that's all.

    Thanks, that's exactly what I needed to hear. I tried it out with R=1kOhm and C=0.1uF and it worked well.
