| The full-scale output of a 8-bit DAC is 10 V. Find the resolution for this digital to analog converter.
A. 39. 2 mV
B. 3.92 mV
C. 3.92 V
D. 0.392 V
Please scroll down to see the correct answer and solution guide.
Right Answer is: A
SOLUTION
For 8-bit DAC, we have
n = 8
and full scale output is
Vfs = 10 V
So, we get
Number of steps = 2n – 1
= 28 – 1
= 255
Hence resolution or step size is
= 39.2 m V
