(1) The internal reference current is supplied from terminal AVCC. Consumption is independent of the ADC10ON control bit, unless a conversion is active. The REFON bit enables to settle the built-in reference before starting an analog-to-digital conversion.
(2) Calculated using the box method: (MAX(–40°C to 85°C) – MIN(–40°C to 85°C)) / MIN(–40°C to 85°C)/(85°C – (–40°C)).
(3) The condition is that the error in a conversion started after tREFON is less than ±0.5 LSB.
(4) The sensor current ISENSOR is consumed if (ADC10ON = 1 and REFON = 1) or (ADC10ON = 1 and INCH = 0Ah and sample signal is high). When REFON = 1, ISENSOR is already included in IREF+.
(5) The temperature sensor offset can be significant. TI recommends a single-point calibration to minimize the offset error of the built-in temperature sensor.
(6) The typical equivalent impedance of the sensor is 51 kΩ. The sample time required includes the sensor-on time tSENSOR(on).
(7) The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.
