i am working on arm cortex m tm4c123h6pm microcontroller. i am measuring voltage using an ADC. i need to design a voltage divider to measure voltage and for that i need to consider the ADC's internal resistance as well. i checked out its value in the datasheet but i don't know whether it is in parallel or series with the pin? plz help
