NOTES: 1. The sensor current I
SENSOR
is consumed if (ADC10ON = 1 and REFON = 1), or (ADC10ON = 1 and INCH = 0Ah and sample signal
is high). When REFON = 1, I
SENSOR
is included in I
REF+
. When REFON = 0, I
SENSOR
applies during conversion of the temperature
sensor input (INCH = 0Ah).
2. The following formula can be used to calculate the temperature sensor output voltage:
V
Sensor,typ
= TC
Sensor
( 273 + T [°C] ) + V
Offset,sensor
[mV] or
V

Sensor
(T
A
= 0°C) [mV]
3. Results based on characterization and/or production test, not TC
Sensor
or V
Offset,sensor
.
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.
