Hi
Our customer is facing a trouble with ADC on F28032.
They guess that ADC output variation become larger when ambient temperature is changed.
-ADC gets DC (2.5V) signal, and 128 sampling data (256us sampling period with 2us cycle) are
performed FFT processing.
-When ambient temperature be warmed or cooled (for the evaluation purpose by Hairdryer),
ADC output variation become larger. And, it causes to failure in the market.
Q#1: Does the following thing is expected behavior?
“ADC output variation become larger when ambient temperature is changed.”
Q#2: Customer use 60MHz clock (4.6MSPS).
According to Errata, there are same issue related to ADC.
Does above customer’s usecase much one of them?
Thanks and Best regards,
HaTa
