    (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
    . The sample time required includes the sensor-on time tSENSOR(on).
    (4)
    The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.
