Question

An 8 bit DAC produces output voltage of 2 V for a binary input of 0110 0100. The output voltage for a binary input of 1011 0011 is

• A. 3.58 V
• B. 4.16 V
• C. 5.25 V
• D. 6.25

Answer 1

The correct option is A 3.58 V

$(01100100{)}_2=(100{)}_{10}$
$(10110011{)}_2=(179{)}_{10}$

$\text{Out put voltage}\propto \text{( decimal equivalent of input binary code)}$

$\text{so,}\frac{x}{2}=\frac{179}{100}$

$x=3.58V$
