16.2.9 Using the Integrated Temperature Sensor
To use the on-chip temperature sensor, select the analog input channel ADC10INCHx = 1010. Any other
configuration is done as if an external channel were selected, including reference selection and
conversion-mode selection. The temperature sensor is located in the REF module of the device and must
be activated by software.
Figure 16-10 shows the typical temperature sensor transfer function. When using the temperature sensor,
the sample period must be greater than 30 µs. The temperature sensor offset error can be large and may
need to be calibrated for most applications (see the device-specific data sheet for parameters).
