Note 4: Human body model, 100pF discharged through a 1.5kΩ resistor. Machine model, 200pF discharged directly into each pin.
Note 5: Thermal resistance junction-to-ambient when attached to a double-sided printed circuit board with 1 oz. foil is 113 °C/W.
Note 6: Reflow temperature profiles are different for packages containing lead (Pb) than for those that do not.
Note 7: Typicals are at T
Note 8: Limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 9: The average current can be calculated from the peak current using the following equation:
Quiescent current will not increase substantially with an SMBus transaction.
Note 10: The accuracy of the LM96000CIMT is guaranteed when using the thermal diode of Intel Pentium 4 90nm processors or any thermal diode with a non-
ideality of 1.011 and series resistance of 3.33Ω. When using a 2N3904 type transistor as a thermal diode the error band will be typically shifted by -?°C.
Note 11: 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 LM96000 and the thermal resistance. See
Note 12: TUE , total unadjusted error, includes ADC gain, offset, linearity and reference errors. TUE is defined as the "actual Vin" to achieve a given code transition
minus the "theoretical Vin" for the same code. Therefore, a positive error indicates that the input voltage is greater than the theoretical input voltage for a given
code. If the theoretical input voltage was applied to an LM96000 that has positive error, the LM96000's reading would be less than the theoretical.
Note 13: This specification is provided only to indicate how often temperature and voltage data is updated. The LM96000 can be read at any time without regard
to conversion state (and will yield last conversion result).
Note 14: Holding the SMBDAT and/or SMBCLK lines Low for a time interval greater than t
the SMBDAT pin to a high impedance state.
