AD7175-2 Datasheet Rev. B & Evaluation Software Inconsistency?

 

I am using AD7175-2 Evaluation Software for EVAL-AD7175-2SDZ and found and inconsistency in some of the settings for the Channel Register Configuration (page 57 and 58) of the AD7175-2 Datasheet Rev. B.

 

Example: The Evaluation Software setting if choosing REF+ is (01001) for Channel Register for either AINPOS0 or AINNEG0, but in the datasheet if choosing REF+ is (10101).

 

The setting does not match between the Evaluation Board and the Datasheet for the following items:

  • Temperature sensor +
  • Temperature sensor -
  • ((AVDD1 - AVSS)/5)+
  • ((AVDD1 - AVSS)/5)-
  • REF+
  • REF-

 

Could you provide which setting is correct?

 

Thanks!
