In my case the output voltage from my sensors is negative. Is it possible to use the ADCs on the Eval-Aducm360 to read out the negative voltage ? I could not find any example to show that it can handle the negative voltage.
Analog voltage inputs into the ADC of the ADuCM360 must follow the datasheet specification. According to page 18, absolute maximum limits for the ADC inputs is -0.3V to 3.96 before you can harm the part. Page 6 shows the input voltage range specifications with a bit more detail and it also says that you can only go from AVDD to AGND, meaning that this device can't work with negative voltage inputs. You will need to invert those sensor signals or bias them up to a positive value before you can send them to the MCU.
