I'm using EVAL-AD2S1200SDZ in my project. I connect al the wires like manual describes (EXC, Exc*, Sin, SinLo, and so on). But when I turn the shaft and read the angle the four less significant bits are off. The connections are not a problem because I changed the new eval-board to the old one and I received 12 bits. I check jumpers but I don't have any idea of what problem is.
