ADS131A04EVM: ADS131A04

Amerdas DK

Part Number: ADS131A04EVM

Tool/software:

We are working on ADS131A04EVM Board. We could communicate with the device and the commands and response working as expected.

The problem we are facing is the DRDY pin shows always LOW. What we understand that its must be high and a HIGH to LOW transition is expected each time a conversion is completed.

Please suggest your comments.

Hi Amerdas,

Were you able to read conversation data from the EVM&ADC?

Hi Dale,

Thank you for the reply.

We can read some data from ADC , but seems its not a proper value.

Hi Amerdas,

Thank you for your information. I forgot to ask you if you were using the ADS131A04EVM GUI software with the PHI controller card in the EVM-PDK. If not, please let me know your connections between the EVM and your controller. Your timing plot including (/SCLK, DIN, DOUT, /CS and /DRDY) will be very helpful to address the issue.

BR,

Dale
