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 1.5kOhm resistor into each pin. Machine Model: 200pF capacitor discharged directly into each pin.

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.
