18.3 Output Range Selection

The D/A output range is determined by the values of the register bits DAPOL, DAG!, and DAG0 in the register at page 2 base+14. When a value is written to this register, the D/A range for the selected channel will be set to the selected value. Each D/A channel can have its own range. To set all channels to the same range, set bit DAUR=0 when selecting the output range. To set a channel to its own range, set DAUR=1 and then select the channel using bits DACH1-0

DAPOL	DAG1	DAG0	DAC output range or function
0	0	0	0 to 5V (unipolar 5V span)
1	0	0	±2.5V (bipolar 5V span)
0	0	1	0 to 10V (unipolar 10V span)
1	0	1	±5V (bipolar 10V span)
0	1	0	Not Used – Setting Ignored
1	1	0	±10V (bipolar 20V span)
