Hi again,
I have run the tests reading the temperature sensor, MVDD and the internaly generated test signal, All readings match with the readings using the evaluation software. Then I realized that I was leaving the negative terminal connected to the Wilson Central Terminal. Without the WCT, (a pure differential signal) the measurements are correct. With the WCT (I wrongly assumed it was GND) the measurements are shifted up by 2.4, which gives a reading of 7FFFFF to a 0V input and a reading of 000000 to a -2.4V. I figured out then that the WCT has something to do with the reading since I haven't set the WCT1/2 registers. Since they are powered down by default I though they wouldn't affect the reading. To be honest I didn't read to much on the WCT so I believe that's where the problem comes from, I will go over the datasheet and see how it goes.
Any suggestion?
Thanks,
Efrain
