(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.
(3) Limits characterized
(4) The typical equivalent impedance of the sensor is 51 kΩ. The sample time required includes the sensor-on time t
SENSOR(on)
(5) No additional current is needed. The V
MID
is used during sampling.
(6) The on-time t
VMID(on)
is included in the sampling time t
VMID(sample)
, no additional on time is needed.
