2.2.3 Wrong VDD33/2 for ADC Internal Input Channel AN11
The ADC internal input channel, AN11, is connected with VDD33/2, but the observed input voltage is not equal to VDD/2.
Work Around
Get the expected input using the below formula:
VDD33/2 = VDD x (598.5/900)
For example, VDD = 3.3V
VDD33/2 = 3.3 x (598.5/900) = 2.1945V
