(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 conditions 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.
(2) When the input voltage (V
I
) at any pin exceeds the power supplies (V
I
< GND or V
I
> V
DD
), the current at that pin should be limited to 5
mA. Parasitic components and or ESD protection circuitry are shown in Figure 2 and Table 1 for the LM95241's pins. Care should be
taken not to forward bias the parasitic diode, D1, present on pins: D1+, D2+, D1−, D2−. Doing so by more than 50 mV may corrupt the
temperature measurements.
(3) Thermal resistance junction-to-ambient when attached to a printed circuit board with 1oz. foil and no air flow:
— VSSOP-8 = 210°C/W
(4) Human body model (HBM), 100pF discharged through a 1.5kΩ resistor. Machine model (MM), 200pF discharged directly into each pin.
Charged Device Model (CDM) simulates a pin slowly acquiring charge (such as from a device sliding down the feeder in an automated
assembler) then rapidly being discharged.
(5) Reflow temperature profiles are different for packages containing lead (Pb) than for those that do not.
