9.2 User Interface
Figure 38 shows the D/A converter circuit. A buffer, U6, buffers the data signals D0–D7
from the Smart Star backplane, and sends them to the D/A converter, U2–U5. Signals D2–
D5 are used to switch the chip select line to identify which D/A converter will perform the
conversion. The model of D/A Converter Card determines the analog output ranges (0 V to
10 V, -10 V to +10 V, or 4–20 mA). The different voltage or current ranges are handled with
different feedback resistors, as shown in Figure 38. A switching regulator provides a regu-
lated power supply for the op-amps.
