Hi  BU:

I have one issue about the AMC1306M25 and need your help.

Customer evaluate the performance of AMC1306 in the high temperature. Please see the below picture.

The red is the actual current waveform  , and blue is the sigma_delta Digital signal reduction , the temperature is 66℃ ,the peak current is 141A

 when increase the temperature to 67℃ (by 1℃) , there is some spike on the peak current , seems there is full scale data output from AMC1306.


Check the data stream from AMC1306, the issue is output "1" with several clocks, could you please help me check what's the reason
