(1)
The sensor current ISENSOR 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 k
. The sample time required includes the sensor-on time tSENSOR(on)
(5)
No additional current is needed. The VMID is used during sampling.
(6)
The on-time tVMID(on) is included in the sampling time tVMID(sample), no additional on time is needed.
