9.3.2. Digital-to-Analog Converters (DAC)

Try these first

1. 1.

   What does a DAC do?

   Hint

   What is the purpose of a DAC in electronics?

2. 2.

   Name one type of DAC.

   Hint

   Think of the DACs we discussed.

3. 3.

   What is the primary function of a DAC?

   • Convert analog to digital
   • Convert digital to analog
   • Store digital data

   Hint

   Think about what happens when you need an analog output.

4. 4.

   True or False: R-2R Ladder DACs are generally less complex than Binary-Weighted DACs.

   • True
   • False

   Hint

   How do the designs differ in terms of components?

5. 5.

   Design a simple R-2R ladder DAC circuit and explain how it converts a 4-bit binary number to an analog voltage.

   Hint

   Think about how binary input affects which resistors are activated.

6. 6.

   Evaluate the trade-offs between using Binary-Weighted DACs versus Delta-Sigma DACs in audio applications.

   Hint

   Explore how accuracy in audio translates into listener experience.
