Digital to Analog conversion? DAC0832?

[aunlu]

I want to make digital to analog conversion using
DAC0832 chip, driven directly by AVR microcontroller.
But DAC chip does not respond to changes in the digital
input (no, the chip is not broken). I tried to implement everything as it is told in the DAC's datasheet. But still it does not work? Is there anyone who tried to do a similar thing? Somebody help....

If the DAC does not respond to the digital signal, then how can you be sure that the "chip is not broken"?

The DAC0832 is a pretty simple chip.
Check every pin for power, ground, vref and appropriate selects (active low for cs, wr and others)

It has a 'pass through' mode if all the selects are tied low. Once you see anything at all, you can work backwards.

I would ask Melone's question, how do you know its not broken? Don't trust anything.

Are you looking at this with an oscilloscope?
