Relationship between input data values and output voltages (continued)
Functional Description (continued)
Apply the voltages for the
The correction voltage input pins are divided into two groups: the high-level output control group and the low-level
output control group, and each group is connected in series with resistors. Each of these resistor series has a total
typical value of 14 k .
This structure is shown in the figure. The typical values of the resistors are shown in parentheses.
Note that since these voltages are resistor divided internally, the voltages applied to the VREF pins should be applied
through a low-impedance circuit. If the voltages are directly applied by the resistor divider, the desired output voltages
may not result.
