(1)
The sensor current I
SENSOR
is consumed if (ADC12ON = 1 and REFON = 1), or (ADC12ON = 1 AND INCH = 0Ah and sample signal is
high). Therefore it includes the constant current through the sensor and the reference.
(2)
The temperature sensor offset can be as much as ±20°C. A single-point calibration is recommended to minimize the offset error of the
built-in temperature sensor.

The typical equivalent impedance of the sensor is 51 k
Ω
. The sample time required includes the sensor-on time t
