(1)
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 included in IREF+.When REFON = 0, ISENSOR applies during conversion of the temperature sensor
input (INCH = 0Ah).
(2)
The following formula can be used to calculate the temperature sensor output voltage:
VSensor,typ = TCSensor ( 273 + T [°C] ) + VOffset,sensor [mV] or
VSensor,typ = TCSensor T [°C] + VSensor(TA = 0°C) [mV]
(3)
Results based on characterization and/or production test, not TCSensor or VOffset,sensor.
(4)
No additional current is needed. The VMID is used during sampling.
(5)
The on time, tVMID(on), is included in the sampling time, tVMID(sample); no additional on time is needed.
