First has anyone used this chip ADS1216 and the IDAC feature on the chip?
I have tried on many occasions to get the IDAC's to work on the ADS1216 and I'm not successful. I'm using an FPGA (artix-7 w/ Vivado 2016.4) to interface with the ADS1216.
I have setup the setup reg on the ADS1216 to use the internal reference and I have also set the range for the IDAC and I have also given the ADS1216s' IDAC a value. After all that I still see no current on the IDAC. I have to use the IDAC's because I'm using and 4 wire temp sensor that requires a current supply.
What do I need to do to get the IDAC to function?
