Hi Omer,
I'm sorry for the confusion. I meant the LM95231BIMM. I checked my old software and the evaluation software. We had the address 0x2B for LM95231CIMM. The datasheet has a typo. Sorry for any inconvenience. I will submit a request to fix this error. Please let me know if this resolve the issue. I am looking forward to hearing from you.
Aaron
