29.3.9 Calibration
The DAC contains a calibration register, DACn_CAL, where calibration values for both offset and gain
correction can be written. Offset calibration is done separately for each channel through the CHxOFFSET
bit-fields. Gain is calibrated in one common register field, GAIN. The gain calibration is linked to the
reference and when the reference is changed, the gain must be re-calibrated. Gain and offset for the
1V25, 2V5 and VDD references are calibrated during production and the calibration values for these
can be found in the Device Information page. During reset, the gain and offset calibration registers are
loaded with the production calibration values for the 1V25 reference.
29.3.10 Opamps
The DAC includes a set of three highly configurable opamps that can be accessed in the DAC module.
Two of the opamps are located in the DAC, while the third opamp is a standalone opamp. For detailed
description see the OPAMP chapter. The register description can be found Section 29.5 (p. 710)
