7.3.3 Temperature Result and Limits

At the end of every conversion, the device updates the temperature register with the conversion result. The data in the result register is in 2's complement format, has a data width of 16 bits and a resolution of 7.8125m°C. Table 7-1 shows multiple examples of possible binary data that can be read from the temperature result register and the corresponding hexadecimal and temperature equivalents.

The TMP119 also has alert status flags and alert pin functionality that use the temperature limits stored in the low limit register and high limit register. The same data format used for the temperature result register is used for data written to the high and low limit registers.
