I 10. How many comparators are required 4 1 to form an 8-bit flash converter? པས:--སྡ°ང་ the bine. ז'יז 13. For a certain 2-bit successive-ap- proximation ADC, the maximum lad- der output is +8 V. If a constant +6 V is applied to the analog input, deter- mine the sequence of binary states. for the SAR. 14. Repeat Problem 13 for a 4-bit suc- cessive-approximation ADC. 17. Determine the output of the DAC in Figure 12-48(a) if the sequence of 4-bit numbers in part (b) is ap- plied to the inputs. The data inputs have a low value of 0 V and a high value of +5 V. 200 ΚΩ Dow 100 ΚΩ DOW 50 ΚΩ D₂ W 25 ΚΩ D3W (a) 10 ΚΩ ww Do D. D₂ Output D3 (b) Figure 12-48 18.
