i have troubles with some AD590JH.
2 or 3 of 1000 pieces makes troubles. ( wrong measurement-values
by factor 2, but linear ). Also the resitance is only 1.3kOhm from output-pin to the case.
I have initiated a Failure Analysis by ADI and
got document. But this component works
normaly at ADI and makes no troubles.
Now i get this component back for more analysis.
But what could i do now?
Maybe the risetime of VDD is not fast enough? or too slow?
Do you have some tips for me to check my circuit?
