Calibrating the PCI-DAS1602/16 

19 

Analog output calibration 

The analog output circuits are calibrated for both gain and offset. Offset adjustments for the analog outputs are 
made in the output buffer section. The tuning range of this adjustment allows for maximum DAC and output 
buffer offsets. Gain calibration of the analog outputs is performed via DAC reference adjustments. 

The analog output calibration system is shown in Figure 6. This circuit is duplicated for both DAC0 and DAC1.
