Question

If the maximum full scale voltage is 10 V, the number of bits of ADC is required to get a resolution of 0.5 mV is

Option 1:

15

Option 2:

18

Option 3:

19

Option 4:

20​

Answer 1

Answer:

15 Is the answer

Answer 2

Answer: 20

Explanation: given resolution = 5mV

                      full scale output = +10V

                      % resolution = (5mV)/10*100

                                             = 0.05

               number of bits = log2 (2*1000)

                                          = 20
