I'm design a board using the iMX28 and I need to read 4 analog values in the range from 0 to 3.3 voltage and I would use the LRADC2..5 channels for this scope.
In the RM is write:
"For input channels (other than BATT, 5V, or VDDIO) with signals larger than 1.85 V,
the divide-by-two option should be set (HW_LRADC_CTRL2_DIVIDE_BY_TWO).
With the DIVIDE_BY_TWO option set, the maximum input voltage is VDDIO – 50mv."
but in the data sheet I the chapter 18.104.22.168 LRADC Electrical Specifications I read:
"DC input voltage 0-1.85 V"
Is it possible to apply an analog signal in the range from 0 to 3.3 voltage to the LRADC2...5 pins?
