DAC8412/DAC8413
Careful attention to grounding is important for accurate
operation of the DAC8412. This is not because the DAC8412 is
more sensitive than other 12-bit DACs, but because with four
outputs and two references, there is greater potential for ground
loops. Because the DAC8412 has no analog ground, the ground
must be specified with respect to the reference.
REFERENCE CONFIGURATIONS
Output voltage ranges can be configured as either unipolar or
bipolar, and within these choices, a wide variety of options
exists. The unipolar configuration can be either positive or
negative voltage output, and the bipolar configuration can be
either symmetrical or nonsymmetrical.

Figure 40 (symmetrical bipolar operation) shows the DAC8412
configured for ±10 V operation. See the
full explanation of reference operation. Adjustments may not be
required for many applications since the AD688 is a very high
accuracy reference. However, if additional adjustments are
required, adjust the DAC8412 full scale first. Begin by loading
the digital full-scale code (0xFFF), and then adjust the gain
adjust potentiometer to attain a DAC output voltage of 9.9976 V.
Then, adjust the balance adjust to set the center-scale output
voltage to 0.000 V.
