Question

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

Open in App

Solution

$(01100100)_{2} = (100)_{10} (10100010)_{2} = (162)_{10}$
Output voltage $\propto$ (decimal equivalent of input binary code)

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

$x = 3.24 V$
