Question:
The basic step of an 8-bit DAC is 12.4 mV. If the binary input \( 00000000 \) represents 0V, determine the output if the input is \( 10110111 \).
The basic step of an 8-bit DAC is 12.4 mV. If the binary input \( 00000000 \) represents 0V, determine the output if the input is \( 10110111 \).
Show Hint
To find the output voltage, multiply the decimal equivalent of the binary input by the basic step value.

- 1.36 V
- 2.27 V
- 5.45 V
- 3.25 V
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
- The decimal equivalent of the binary input \( 10110111_2 \) is 183.
- The output voltage is calculated as
\[
V_{out} = 183 \times 12.4 \, \text{mV} = 2.27 \, \text{V}
\]
Conclusion: The correct output voltage is given by option (b).
Conclusion: The correct output voltage is given by option (b).
