Challenge Problems
Push your limits with challenges.
Question 1
A 4-bit Weighted Resistor DAC requires resistors of R, R/2, R/4, and R/8 to be calculated for a specification of Vref = 5V. Determine the output voltage for the input 1101.
💡 Hint: Follow the weighted resistor formula carefully.
Question 2
What would be the effect on the output voltage of a Weighted Resistor DAC if one of the resistors is incorrectly valued due to manufacturing tolerance? Discuss how this impacts performance.
💡 Hint: Consider how each resistor contributes to overall voltage as you analyze the issue.
