General, не там смотрите. 17.2.7 Using the Integrated Temperature Sensor To use the on-chip temperature sensor, the user selects the analog input channel INCHx = 1010. Any other configuration is done as if an external channel was selected, including reference selection, conversion-memory selection, etc. The typical temperature sensor transfer function is shown in Figure 17–10. 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 device-specific datasheet for parameters. Selecting the temperature sensor automatically turns on the on-chip reference generator as a voltage source for the temperature sensor. However, it does not enable the VREF+ output or affect the reference selections for the conversion. The reference choices for converting the temperature sensor are the same as with any other channel.
