DAC Output Buffer Lifetime Drift

The offset of the DAC output buffer can drift over lifetime if the device is powered with the DAC output buffer disabled.

Work Around

Keep the DAC output buffer enabled (OUTEN in DACn.CTRLA is ‘1’) continuously or compensate by measuring the DAC output voltage offset with the ADC and adjust the DAC data register value (DATA[9:0] in DACn.DATA) accordingly.
