Value guaranteed by design, not 100% tested in production.

(2)

Value guaranteed by characterization, not 100% tested in production.

(3)

The error is the average result of 100 times and represents the temperature error of chip junction at the location

where it is placed on die. The chip self-heating shall be considered when testing ambient temperature.

(4)

The error caused by ADC conversion and provided temperature calculation formula is not included.

(5)

Note: ADC2 clock should not be configured greater than 5MHz and the sampling time should greater than

ts_temp when use the high precision temperature sensor by ADC conversion.
