Sweet, thanks mate. Fortunately i didn't pull them all apart, and have found the clip you're talking about in another one. Now i face the tssop to dip problem again. Maybe i'll get away with etching my own pcbs rather than paying the high prices for adapters. Cheers.

Hey, I salvaged some LCD screens from some old cordless phones. I'd like to play around driving it with a microprocessor, but i can't work out how to access the wires inside that plastic ribbon. Is there a kind of clamp or suchlike which does this? As far as i can tell the lines in the ribbon are ~0.5mm apart. Thanks very much.

Hey guys, thanks for your help. Thanks for digging up that reference sarma, i'll definitely use it to test out this dac. This dual rail chip sure is a headache. For audio needs i'll use the negative reference too. Thanks guys.

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 :)

Hey guys, i'm very new to electronics so please bear with me :) I'm trying to use a DAC chip which is giving me all sorts of headaches. At present I need to supply a reference voltage of -12v. How am I to source -12v? The only way i can get my multimeter to read that is by swapping the positive and negative leads? Is this the right way to go? Thanks very much for your help :) Nick
