3. Refer to Fig. 1 in the handout; obtain the circuit output in PSpice for some of the digital input combinations given in Table. 1. Assume that 5V analog input and 0V analog input correspond to a digital ‘1' and a digital .0', respectively, and that the DAC outputs are converted so that positive voltages are obtained. Also, a. What is the range, precision and resolution of the DAC? b. What are the output voltages values when the input is equal to 0000, 0001' or 1011? How do you justify the DAC output voltage values? Qualitatively, what would you do to achieve the exact analog results given in Table. 1 for the corresponding digital inputs? c.
