3.3.3. Common DAC Architectures

Try these first

1. 1.

   What does a DAC do?

   Hint

   Think of how sound is produced from digital files.

2. 2.

   Name one application of a DAC.

   Hint

   Consider your favorite music device.

3. 3.

   What is the primary function of a DAC?

   • Convert analog into digital
   • Convert digital into analog
   • Store digital data

   Hint

   Think about how digital music is played on speakers.

4. 4.

   True or False: The R-2R Ladder DAC is known for its complexity in design.

   • True
   • False

   Hint

   Recall the resistor structure mentioned earlier.

5. 5.

   Consider a Binary-Weighted DAC that's used in an audio system. If the input code changes rapidly, how would this affect the audio quality? Discuss potential issues.

   Hint

   Investigate the impact of glitches on sound.

6. 6.

   Design an R-2R Ladder DAC for a 3-bit input, detailing the connections and how it converts the input into an analog signal.

   Hint

   Sketch out a circuit diagram to visualize the R-2R ladder.
