hello
Anyone knows where i can find ADC calculator pic microcontroller
thanks
 

D = (A/Vref) * resolution.

Most PICs have 10-bit ADC so the result is (Analog input/Vref) * 1023

Vref can be VDD, an internal reference if the PIC has one or an external reference if the pin is configured.

The input voltage can't be higher than Vref or the ADC module can be damaged.

Brian.
