PRODUCT SPECIFICATION
Absolute Maximum Ratings
Notes:
1. Absolute maximum ratings are limits beyond which operation may cause permanent damage to the device. These are stress
2. Human Body Model: 100pF capacitor discharged through a 1.5k Ω resistor into each pin. Machine Model: 200pF capacitor
Electrical Characteristics
(-40°C ≤ T
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
5. Accuracy (expressed in °C) = Difference between the FM75 output temperature and the measured temperature.
