Need ADC demo guidelines

I am beginner in ADC.

I am working with demo project of ADC. It is working perfectly but I want some information about ADC demo.


1. What is Sample need to trigger event in ADC_INIT_CHANNEL_STRUCT?? If I am increasing it then reading of ADC output seems fast...!! I dont understand that logic.

2. Why Event is required?

3. What is the purpose of Circular buffer size? Is it doing some kind of averaging?? What I need to do to get average output (..Not Manually).

4. If reference voltage is 3.31V (I measured with Multimeter) then is it possible to give more that 3.31V as input say 10V.

5. What is Formula that is converting Analog input Voltage into 16bit Digital output ?


- I read that Max Rang of Vin is (VREFH * 31/32) from K60P144M120SF3.pdf (SnapShot attached).


Actually I am trying to figure it out. I read MQXIOUG, TWR‐K60D100M, K60P144M120SF3.  But I am helpless. Cant get brief idea.


Can someone help me to sort this out. I am so much confused..
