Note 3:
Reflow temperature profiles are different for packages containing lead (Pb) than for those that do not.
Note 4:
Human body model, 100 pF discharged through a 1.5 k
Ω
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.
Note 5:
Thermal resistance junction-to-ambient when attached to a 4 layer printed circuit board per JEDEC standard JESD51-7:
– 14-lead LLP = 90°C/W (no thermal vias, no airflow)
– 14-lead LLP = 63°C/W (1 thermal via, no airflow)
– 14-lead LLP = 43°C/W (6 thermal vias, no airflow)
– 14-lead LLP = 31°C/W (6 thermal vias, 900 ln. ft. / min. airflow)
Note, all quoted values include +15% error factor from nominal value.
Note 6:
Typicals are at T
A
= 25°C and represent most likely parametric norm.
Note 7:
Limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 8:
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 5)
for the thermal resistance to be used in the self-heating calculation.
Note 9:
The accuracy of the LM95214CISD is guaranteed when using a typical MMBT3904 diode-connected transistor. For further information on other thermal
diodes see applications

"Diode Non-ideality" or send email to hardware.monitor.team@national.com.
Note 10:
Quiescent current will not increase substantially with an SMBus communication.
Note 11:
This specification is provided only to indicate how often temperature data is updated. The LM95214 can be read at any time without regard to conversion
state (and will yield last conversion result).
Note 12:
The output rise time is measured from (V
IN(0)
max 0.15V) to (V
IN(1)
min + 0.15V).
Note 13:
The output fall time is measured from (V
IN(1)
min + 0.15V) to (V
IN(0)
max 0.15V).
Note 14:
Holding the SMBDAT and/or SMBCLK lines Low for a time interval greater than t
TIMEOUT
will reset the LM95214's SMBus state machine, therefore setting
SMBDAT and SMBCLK pins to a high impedance state.
