Other Parts Discussed in Thread: ADS122C04
Hi Team,
Good afternoon, I have a customer looking to test out the IDAC function on the ADS122C04EVM.
They are using IDAC1 with AIN3 as the output. They are trying to set this up in the GUI, however the MUX to route IDAC1 to AIN3 doesn't program the registers properly (Should be 0x80 not 0x40 based on the datasheet):
Update: The customer was able to get IDAC2 routed to AIN3 via the configuration for connecting IDAC1 to AIN0. However, the current sources are still disabled. In order to enable them, you have to open the data analysis section and start a conversion. From that point on, the current sources stay enabled even if conversions are not happening. The customer suspects that this is related to POWERDOWN command happening at startup, could you elaborate more on this behavior?
Please let me know there is a way around this or if you have any questions.
Regards,
~John
