5.4 D/A Calibration

In a way similar to the ADCAL.EXE program, the DACAL.EXE program leads you through the whole D/A calibration procedure.

You can either use the on-board -5 V (-10 V) internal reference voltage or use an external reference. If you use an external reference, connect a reference voltage within the range ±10 V to the reference input of the D/A output channel you want to calibrate. Adjust the full scale (gain) of D/A channel 0 and 1, with VR4 and VR5 respectively.

Note! Using a precision voltmeter to calibrate the D/A outputs is recommended.

Set the D/A data register to 4095 and adjust VR3 until the D/A output voltage equals the reference voltage minus 1 LSB, but with the opposite sign. For example, if Vref is -5 V, then Vout should be +4.9959 V. If Vref is -10 V, Vout should be +9.9918 V.
