5.2 Operating Ratings

See(1)(7)
Operating Temperature Range(1)(7) 0°C to +125°C
Electrical Characteristics Temperature Range TMIN≤TA≤TMAX
LM95231BIMM, LM95231CIMM 0°C≤TA≤+85°C
Supply Voltage Range (VDD) +3.0V to +3.6V
(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is ensured to be functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the Electrical Characteristics. The ensured specifications apply only for the test condition listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Operation of the device beyond the Maximum Operating Ratings is not recommended.
(7) Thermal resistance junction-to-ambient when attached to a printed circuit board with 1oz. foil and no airflow:
— VSSOP-8 = 210°C/W
