In an ADC, differential nonlinearity (DNL) describes deviation of?

  • AAn individual code-bin width from the ideal 1-LSB step
  • BThe supply voltage from zero
  • CThe clock duty cycle from 100 percent
  • DThe number of output bits from an integer
Report an error
Correct Answer: A. An individual code-bin width from the ideal 1-LSB step
Explanation: DNL measures how much each actual transition step or code-bin width differs from the ideal one-LSB size.
