Hi All,
I think that there are various phenomena when it comes to failure mode, but is there any symptoms that the output voltage becomes a fixed value in that?

Hello Koji,
Thanks for considering Texas Instruments in your design. Depending on which datasheet specification is exceeded, you may observe different failure behavior and the output voltage may vary. One quick way to check if the part has failed, would be to see if the quiescent current and offset voltage are higher than expected. Another more tedious check would be to see what kind of % error you are getting. Fortunately there is a handy tool (figure 1 below) on the INA213-Q1 product page that can help you quickly see what amount of error you should be seeing for some given operating conditions.
