Question

A 8-bit binary DAC produces ouput voltage of 2 V for a binary input (01100100). The output voltage for the binary input(10100010) is ______V.

• A. 3.24

Answer 1

The correct option is A 3.24
$(01100100{)}_2=(100{)}_{10}(10100010{)}_2=(162{)}_{10}$
Output voltage $\propto$ (decimal equivalent of input binary code)

Let $(10100010{)}_2=(x{)}_{10}\frac{5}{2}=\frac{162}{100}$

x= 3.24 V
