Dear Team,
a customer evaluates the ADS131E08 EVM and noticed that all raw data are even numbers.
Just some numbers as example from a full sweep (negative saturation to positive saturation):
| 7FFFFF |
| 791CE2 |
| 5A7058 |
| 2D7CE2 |
| F9951C |
| C6BCAA |
| 9CFB9A |
| 83204E |
| 800000 |
This was noticed with all 8 channels.
How could this be explained?
Thanks and best regards
Martin
Hi Martin,
I still do not have an explanation for this. I have verified that, on the current version of the EVM hardware/software I'm using, I do not see this issue upon exporting the raw data to an Excel file. Can you confirm that your customer is using the same version?
ADS131E08 Evaluation Software and Firmware Version
Also, how are they exporting and saving the data? They should be using the Save tab, then selecting the channels and data format to save. "Data - Codes" will save the raw hexadecimal ADC output.
