An 8-bit unipolar (all analog output values are positive) digital-to-analog converter (DAC) has a full-scale voltage range from 0 V to 7.68 V. If the digital input code is 10010110 (the leftmost bit is MSB), then the analog output voltage of DAC (rounded off to one decimal place) is _______ V.

Given:

8 bit unipolar DAC

Vrange = 7.68 V

i / p = 10010110

Formula:

DAC o/p = Resolution * decimal equivalent

Where, resolution \( = \frac{V}{{{2^n} - 1}}\) full scale

n = no. of bit

Calculation:

Decimal equivalent of 10010110 = 15010

DAC o / p = Resolution × decimal equivalent

\(\frac{{7.68}}{{{2^8} - 1}} \times 150\)

DAC o / p = 4.51 V
