Question:medium

Resolution of an 8-bit ADC with 5V reference is

Show Hint

Quick fractional shortcuts for common bit sizes: - 8-bit resolution scale factor is roughly \( \frac{1}{256} \approx 0.39% \) of total span. - \( 5\text{ V} / 256 \approx 19.53\text{ mV} \) Memorizing power-of-two divisions saves valuable calculation time during competitive multiple-choice exams!

\(5\text{ V} \)
\(2.5\text{ V} \)
\(19.5\text{ mV} \)
\(39\text{ mV} \)

Show Solution

The Correct Option is C
