DAC8412/DAC8413
Typical Performance Characteristics
found that this is large enough to stabilize this circuit. Larger
resistor values are acceptable, provided that the drop across the
resistor doesn’t exceed a V
volts and a maximum current of 2.75 mA, then the resistor
should be under 200
Using two separate references is not recommended. Having two
references could cause different drifts with time and tempera-
ture; whereas with a single reference, most drifts will track.
Unipolar positive full-scale operation can usually be set with a
reference with the correct output voltage. This is preferable to
using a reference and dividing down to the required value. For a
10 volt full-scale output, the circuit can be configured as shown in
Figure 2. In this configuration the full-scale value is set first by
adjusting the 10 k resistor for a full-scale output of
9.9976 volts.

Single +5 Volt Supply Operation
For operation with a +5 volt supply, the reference should be set
between 1.0 and +2.5 volts for optimum linearity. Note that
lower reference voltages will have greater effects due to noise.
Figure 5 shows a REF43 used to supply a +2.5 volt reference
voltage. The headroom of the reference and DAC are both suf-
ficient to support a +5 volt supply with 5% tolerance. V
