Calculation of actual analog input from bipolar ADC's output I have a $14$-$\textrm{bit}$ ADC which can take $-10\textrm{ V}$ to $10\textrm{ V}$ as input. So, $0$ to $16383$ (digital) represents the voltage from $-10$ to $10$. If I want to get the actual voltage from the digital values I am getting, what should I do? i.e. if $8192$ is coming then my program should identify it as $0\textrm{ V}$. 

Please help me out. If my understanding is wrong, please correct me.
Your understanding is right. First subtract the bias, and then apply scaling to get analog actuality.
