Hi Haresh, This sounds like a random failure. Was this a field failure? Or a failure in your normal test flow? We can possibly narrow down the issue. How are you reading the data? Are you using the RDATAC mode reading directly from the device or are you using the RDATA command? How are you determining when the results are to be read? Are you using the DRDY or are you using a time based method? It may be possible that the data rate is not what you think. I would verify with an oscilloscope that the part is signalling with DRDY transitioning from high to low and at the data rate programmed to the device. Best regards, Bob B
