7. Digital-to-Analog Conversion (DAC)

Try these first

1. 1.

   What is a DAC?

   Hint

   Think about how digital recordings translate into sound.

2. 2.

   How does resolution affect output levels?

   Hint

   Consider binary systems; each additional bit doubles levels.

3. 3.

   What is the primary function of a Digital-to-Analog Converter?

   • To convert analog signals to digital
   • To convert digital signals to analog
   • To amplify signals

   Hint

   Think about the applications requiring sound or analog signals.

4. 4.

   True or False: A higher resolution in DAC equates to fewer output levels.

   • True
   • False

   Hint

   Consider how bits represent binary numbers.

5. 5.

   If a DAC has a resolution of 4 bits and a reference voltage of 10V, compute the maximum output and the output for a digital input of 5.

   Hint

   Utilize the DAC output formula.

6. 6.

   Design a simple input/output scenario for a Sigma-Delta DAC being used in an audio circuit. What factors would be most crucial?

   Hint

   Connect audio application needs to DAC design considerations.
