NOTES: 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. 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.
