Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: All voltages are measured with respect to GND, unless otherwise noted.
Note 3: When the input voltage (V
components and/or ESD protection circuitry are shown below for the LM63's pins. The nominal breakdown voltage of D3 is 6.5 V. Care should be taken not to
forward bias the parasitic diode, D1, present on pins D+ and D−. Doing so by more than 50 mV may corrupt temperature measurements. An "X" means it exists
in the circuit.
Note 4: Human body model, 100 pF discharged through a 1.5 kΩ resistor. Machine model, 200 pF discharged directly into each pin. See
ESD Protection Input Structure.
Note 5: Thermal resistance junction-to-ambient when attached to a printed circuit board with 2 oz. foil is 168°C/W.
Note 6: See the URL “http://www.national.com/packaging/” for other recommendations and methods of soldering surface mount devices.
Note 7: “Typicals” are at T
Note 8: Limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 9: The supply current will not increase substantially with an SMBus transaction.
Note 10: 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 LM63 and the thermal resistance. See
Note 11: The output rise time is measured from (V
Note 12: The output fall time is measured from (V
Note 13: Holding the SMBData and/or SMBCLK lines Low for a time interval greater than t
