Specifications

(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. TI recommends a single-point calibration 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.

No load at the output pin, DAC12_0 or DAC12_1, assuming that the control bits for the shared pins are set properly.
