Question 1.
What does R-2R refer to in an R-2R Ladder DAC?
Show hintHide hint
Think about the resistor values needed in this configuration.
Question 2.
What is the primary function of a DAC?
Show hintHide hint
Consider what DAC stands for.
3Question 3.
What does the R-2R Ladder DAC use to create an analog output?
- A binary tree structure
- A ladder of resistors
- A series of capacitors
Show hintHide hint
Focus on the name and what it suggests about structure.
4Question 4.
True or False: The R-2R DAC is less scalable than binary-weighted DACs.
- True
- False
Show hintHide hint
Think about the fabrication difficulty related to resistor quantity.
Question 5.
Design an R-2R Ladder DAC for 8 bits of input to produce an output of 10V. Determine the values needed for resistors and the layout considerations required.
Show hintHide hint
Calculate the ratio of Vout to Vref and deduce resistor values accordingly.
Question 6.
Critique the efficacy of an R-2R Ladder DAC compared to a Current-Steering DAC in an audio playback application. Discuss performance metrics.
Show hintHide hint
Consider the specific requirements of the application and how each DAC architecture meets them.
