(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its rated operating conditions.
(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 the table below for the LM95214's pins.
(3) Human body model, 100 pF discharged through a 1.5 kΩ resistor. Machine model, 200 pF 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.
(4) Reflow temperature profiles are different for packages containing lead (Pb) than for those that do not.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its rated operating conditions.
(2) Thermal resistance junction-to-ambient when attached to a 4 layer printed circuit board per JEDEC standard JESD51-7:
– 14-lead WSON = 90°C/W (no thermal vias, no airflow)
– 14-lead WSON = 63°C/W (1 thermal via, no airflow)
– 14-lead WSON = 43°C/W (6 thermal vias, no airflow)
– 14-lead WSON = 31°C/W (6 thermal vias, 900 ln. ft. / min. airflow)
Note, all quoted values include +15% error factor from nominal value.

(1) Typicals are at T
A
= 25°C and represent most likely parametric norm.
(2) Limits are specified to AOQL (Average Outgoing Quality Level).
(3) Local temperature accuracy does not include the effects of self-heating. The rise in temperature due to self-heating is the product of the
internal power dissipation of the LM95214 and the thermal resistance. See Note 2 under Operating Ratings table for the thermal
resistance to be used in the self-heating calculation.
(4) The accuracy of the LM95214CISD is ensured when using a typical MMBT3904 diode-connected transistor. For further information on
other thermal diodes see applications DIODE NON-IDEALITY.
