OK well I finally managed to get a TLV5618 DAC working with an Arduino board. What a nightmare that was... So I can replace my noisy old ladder DAC with a proper 12-bit one.
So I now have a 0 - 4.9v signal coming out of a DAC, and I need to make it -5 to +5v. Does anyone have any good ideas how to do this? I tried hooking it up to the TL082 circuit I used with my ladder, but all I can get now is a constant +15v from the output...
Strange...
Any ideas would be greatly appreciated...
