For Max 10 FPGA Dev. kit, I've ever been such similar DAC issue, apparently Altera does not advise DAC examples, sorry for my less further searching, the only thing I can be of help is this DAC8551 datasheet (http://www.ti.com/lit/ds/symlink/dac8551.pdf), which from my colleague, he got this from Terasic, just for one MAX 10 NEEK bought there before, by chance DAC8551 is used as well.
Actually, there goes with some dac_sma examples with MAX 10 NEEK CD-ROM (
