Notes:

1.

14b measurement resolution (default). Values apply to the full operating temperature and voltage range of the device.

2.

±0.1 °C: +35.8 °C to 41 °C; ±0.13 °C: 20.0 °C to 70.0 °C; ±0.25 °C: –40 °C to +125 °C.

3.

Time to reach 63% of final value in response to a step change in temperature. Actual response time will vary

dependent on system thermal mass and air-flow.
