I would like to ask about LRADC of i.MX28.
From the description in i.MX28 datasheet, the power source of LRADC seems to be VDDA. Right?
And the datasheet says that the maximum voltage of LDRADC is 1.85V.
Is it possible for LRADC to operate correctly for 1.85V input to LRADC, in the situation that VDDA is lower than 1.85V?
The reference voltage, the internal Bandgap reference, for the ADC is always 1.85V?
