NOTES:
1. The sensor current ISENSOR is consumed if (ADC12ON = 1 and REFON=1), or (ADC12ON=1 AND INCH=0Ah and sample signal
is high). When REFON = 1, ISENSOR is already included in IREF+.
2. The temperature sensor offset can be as much as
±20_C. A single-point calibration is recommended in order to minimize the offset
error of the built-in temperature sensor.
3. The typical equivalent impedance of the sensor is 51 k
Ω. The sample time required includes the sensor-on time tSENSOR(on)
4. No additional current is needed. The VMID is used during sampling.
5. The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.

NOTES:
1. No load at the output pin, DAC12_0 or DAC12_1, assuming that the control bits for the shared pins are set properly.
2. Current into reference terminals not included. If DAC12IR = 1 current flows through the input divider; see Reference Input
specifications.
3. PSRR = 20*log
{ΔAVCC/ΔVDAC12_xOUT}.
4. VREF is applied externally. The internal reference is not used.
