Hi guys the problem is solved. there is a Vrefint in my ADC register where i can read the Voltage and found the error. Thanks for all for your kind support.
Hi ,
Thanks for your valuable reply.
My hardware team is given the VDDA with 3.3V the same as VDD and they are not cared about the error, but i am not satisfied with the result. so i am possible to find the error on my own so that i can obtain a best result by reducing the error.

I need to measure the 3.3V input given to my ADC input pin. but the reference to AVref is varying from 3.28 to 3.33 because of this my error also increasing, and if i am calibrating at the time the Voltage is 3.28 but after some time its varying to 3.31... so is it any possibility for measuring...
