Notes:
1. Absolute maximum ratings are limits beyond which operation may cause permanent damage to the device. These are stress
ratings only; functional operation at or above these limits is not implied.
2. Human Body Model: 100pF capacitor discharged through a 1.5k
discharged directly into each pin.
resistor into each pin. Machine Model: 200pF capacitor

Notes:
3. These specifications are guaranteed only for the test conditions listed.
4. This specification only indicates how often temperature information is updated to the Temperature Register. The FM75 can
be read at any time without interrupting the temperature conversion process.
5. Accuracy (expressed in °C) = Difference between the FM75 output temperature and the measured temperature.
