DAC4814
FIGURE 3. Analog Connections for
±
10V DAC Output.
FIGURE 4. Analog Connections for 0 to +10V DAC Output.
0 To –10V Output Range
For 0 to –10V unipolar outputs connect the DAC4814 as
shown in Figure 5. Connect the MODE to logic low (GND)
for reset to unipolar zero.
CONNECTION TO DIGITAL BUS
Cascaded Bus Connection
Multiple DAC4814s can be connected to the same CLK and
DATA input lines in two ways. Since the output of the DAC
shift register is available, any number of DAC4814s can be
cascaded on the same input bit stream as shown in Figure 6.
This arrangement allows all DACs in the system to be
updated simultaneously and requires a minimum number of
control signal inputs. However, up to 48N CLK cycles may
be required to update any given DAC, where
N = number of DAC4814s.
Parallel Bus Connection
Several DAC4814s can also have their DATA inputs con-
nected in parallel as shown in Figure 7. This allows any
DAC in the system to be updated in a maximum of 48 CLK
cycles.
