An ideal 10-bit ADC has an input range of 0 to 5.12 V. Using 2^N quantization levels, the nominal voltage represented by one LSB is?

  • A0.5 mV
  • B5 mV
  • C10 mV
  • D50 mV
Report an error
Correct Answer: B. 5 mV
Explanation: A 10-bit ADC has 1024 levels. 5.12 V / 1024 = 0.005 V = 5 mV per LSB under this convention.
