temperature detection circuit is active.

Ambient temperature (in the constant temperature bath) [°C]
*2 This characteristic was measured in 150 µs of the conversion time (comparison time) after canceling SLEEP status by placing the
device in the constant temperature bath.
The temperature detection circuit measures temperature inside the device. Depending on the use environment, the difference
between the measured temperature and the ambient temperature may be increased. When using the measured temperature as
the ambient temperature, prepare an appropriate conversion table according to the use environment.
