(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:

(3) The typical equivalent impedance of the sensor is 51 kΩ. The sample time required includes the sensor-on time t
SENSOR(on)
.
(4) No additional current is needed. The V
MID
is used during sampling.
(5) The on-time t
VMID(on)
is included in the sampling time t
VMID(sample)
; no additional on time is needed.

(1) The cumulative program time must not be exceeded when writing to a 64-byte flash block. This parameter applies to all programming
methods: individual word/byte write and block write modes.
