Hello audioguru how are you? Thankyou for your response. It is perfect that you are an audio guru, because this is the exact application i eventually have in mind with all this DAC business :) The DAC in question is just 8-Bits, i know this is less than ideal for audio - but you've got to start somewhere right? This is the circuit I'm trying to setup at the moment: To be honest i'm a little confused. From what i can gauge the reference voltage goes in at pin 3 & 13, and you get your analogue out at pin 4. Although my experiments so far don't seem to confirm this. Also all these different voltage inputs are confusing. Any help you can give would be greatly appreciated. I managed to get some audio sampling (at shocking quality) with my own resistor ladder, although they weren't precision matched resistors so I suppose that wouldn't help. Also i only provided GND as a negative voltage so that mightn't help either might it as audio is bipolar is that right? Also, this is the datasheet if that helps: http://www.dse.com.au/isroot/dse%5Csupport/Z6834.pdf Thankyou very much for your help :)
