11. An 8-bit DAC has a reference voltage of 9 V. The binary input is
11001100. Find
the analog output voltage.
Sol：
8 bit DAC是256階
11001100=204
(9/256)*204=7.171875
12. The binary data from the computer in a certain application are expected
to go from 00000000 to only 00111111. These data are the input of a DAC. The
analog output should go 0-5V. Find the DAC reference voltage necessary to
make this happen.
Sol：
16進制是3FH
換算成十進制是63
13. An 8-bit ADC has a reference voltage of 12V and an analog input of 3.7V.
Find the binary output.

7. Draw the circuit of a noninverting amplifier with a gain of 30 and draw
the pin numbers of the 8-pin 741 general-purpose op-amp. Power supply voltage
is 正負 15V.
Sol：
10. Sketch the output of an integrator circuit that has an input waveform
shown in Figure 3.60 (assume RC=1).
Sol：
18. Draw the circuit of a low-pass filter with fc=1kHz and a gain of 10. Use
R=1kΩ.
