Note: An x indicates that the diode exists.
Note 3:
See AN-450 “Surface Mounting Methods and Their Effect on Product Reliability” or the section titled “Surface Mount” found in a current National
Semiconductor Linear Data Book for other methods of soldering surface mount devices.
Note 4:
Human body model, 100 pF discharged through a 1.5 k
resistor. Machine model, 200 pF discharged directly into each pin.
Note 5:
Thermal resistance of the QSOP-16 package is 130C/W, junction-to-ambient when attached to a printed circuit board with 2 oz. foil.
Note 6:
Typicals are at T
A
= 25C and represent most likely parametric norm.
Note 7:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8:
The Temperature Error specification does not include an additional error of
±
1C, caused by the quantization error.
Note 9:
The Temperature Error will vary less than
±
1.0C for a variation in V
CC
of 3V to 3.6V from the nominal of 3.3V.
Note 10:
Quiescent current will not increase substantially with an active SMBus.
Note 11:
This specification is provided only to indicate how often temperature data is updated. The LM91 can be read at any time without regard to conversion state
(and will yield last conversion result).
Note 12:
Holding the SMBData and/or SMBCLK lines Low for a time interval greater than t
TIMEOUT
will cause the LM91 to reset SMBData and SMBCLK to the IDLE
state of an SMBus communication (SMBCLK and SMBData set High).
