Find the number of discrete voltages provided by the nbit DA

Find the number of discrete voltages provided by the n-bit DAC for the following: n=8 b. n=12

Solution

Ans) The no discrete voltages provided by n-bit DAC is 2ⁿ

For n=8 no of voltage levels is 2⁸=256

For n=12 no of voltage levels is 2¹²=4096
