Q. How many bits will a D/A converter use so that its full-scale output voltage is 5 V mid is resolution is at the most 10 mV?

Option
a) 5
b) 7
c) 9
d) 11

Read Solution (Total 1)

9 bits
as the full scale voltage is 5 v and the minimum resolution is 10mv
so the number of divisions required are 500
now number of bits be x
2^x = 500
x = 9
