BASIC APPLICATIONS
PROGRAMMING WINDOW DETECTOR
Figure 28 shows the DAC8222 used in a programmable window
detector configuration. The required upper and lower limits for
the test are loaded into DAC A and DAC B. If a signal at the
test input is not within the programmed limits, the output will
indicate a logic zero.
MICROPROCESSOR INTERFACE CIRCUITS
The DAC8222’s versatile loading structure greatly simplifies in-
terfacing to 16-bit bus systems; it also reduces the number of
“glue” logic components. Data loading into its 12-bit wide data
input is achieved by use of only two control signals, WR and
LDAC. DAC selection is controlled with a single DAC A/DAC B
line.
Figures 29 and 30 show how easily the DAC8222 interfaces
with the 8086 and 68000 16-bit microprocessors.
