ADS1278 doesn't work?

Other Parts Discussed in Thread: ADS1278

I've designed an 8-ch analog signal measurement device by using an ADS1278, but it didn't work. The schematic was in the following. Is there anyone who could help me to figure out what I have missed in the design? Thank you.

Hi Sunglin,

From your other post, I thought the ADS1278 was communicating successfully in your design.

Can you tell us more about what you are trying to do and what is not working?

Best Regards,

Hi Ryan,

I have read the datasheet in detail and then I found that I forgot to pull-down the DIN and pull-up the nSYNC. Now the design works as expected. Thank you very much.
