Propose a digital to analogue converter circuit using 1 op amp and 3 resistors (R1=200 kΩ, R2
=100 kΩ, and Rf = 10 kΩ). The sequence of two binary codes is applied and represented by the
waveforms in Figure 3. A high level (2.5 V) is a binary 1 and low level (0 V) is a binary 0. The
least significant digit is D0. Draw circuit diagram, show the calculation involved and sketch the
output waveform.
