Hi guys!
As a result of a project that we needed the part for (but we had left over) I will soon be in possesion of two Analog Devices AD5791ARUZ DACs: 20bit, low noise high accuracy DACs. These things cost about 55 Euros in 1-off quantities on Farnell.
I would like to use them (In combination with some very good reference ICs I also have) to build my own precision voltage source this summer. Usually, I would prototype this kind of stuff by doing a board, seeing if it works, and if not, start over. But as this is a 55 euro DAC, I can't just go and buy a few more if stuff breaks (because I can't warrant the cost in a personal project). I was wondering what techniques I could use to allow me to remove the part safely, without damage, in case the performance of the system is bad. One option would be to use a break outboard, and put the part on there. This should be ok in this application, since I don't think it will impact performance, but I was wondering if there were any other methods that I was unaware of that I could use for this.
