      Question

      In a 4-bit DAC, reference voltage is 5 Volts , then

      analog voltage corresponding to binary data is 1001 is _______
      A 5 volts. Correct Answer Incorrect Answer
      B 3 volts. Correct Answer Incorrect Answer
      C 4 volts. Correct Answer Incorrect Answer
      D 2 volts Correct Answer Incorrect Answer

      Solution
