3.3. Digital-to-Analog Converter (DAC)

Try these first

1. 1.

   What is the primary function of a DAC?

   Hint

   Think about what you hear from digital devices.

2. 2.

   Name one common application of DACs.

   Hint

   Where do you experience sound from digital sources?

3. 3.

   What is the main role of a DAC?

   • Convert digital to analog
   • Convert analog to digital
   • Enhance audio fidelity

   Hint

   Consider the direction of the conversion.

4. 4.

   True or False: Higher resolution in a DAC results in less precise outputs.

   • True
   • False

   Hint

   Review what resolution means in the context of digital signals.

5. 5.

   Consider a DAC with a 12-bit resolution. How many discrete levels can it produce? Discuss the implications of this resolution in high-fidelity audio applications.

   Hint

   Think about binary powers when calculating levels.

6. 6.

   Design a simple R-2R ladder DAC for a segmented application where you output control signals to different devices. Explain its advantages in this setting.

   Hint

   Review how the ladder layout can affect output variability and ease of design.
