1. Settling within ±1 LSB
2. The INL is measured for 0 + 100 mV to VDACR 100 mV
3. The DNL is measured for 0 + 100 mV to VDACR 100 mV
4. The DNL is measured for 0 + 100 mV to VDACR 100 mV with VDDA > 2.4 V
5. Calculated by a best fit curve from VSS + 100 mV to VDACR 100 mV
6. VDDA = 3.0 V, reference select set for VDDA (DACx_CO:DACRFS = 1), high power mode (DACx_C0:LPEN = 0), DAC set to
0x800, temperature range is across the full range of the device
