DC Electrical Characteristics (Notes 2, 7) (Continued)
Note 8: Accuracy is defined as the error between the output voltage and 10 mV/˚F times the device’s case temperature at specified conditions of voltage, current,
and temperature (expressed in ˚F).
Note 9: Nonlinearity is defined as the deviation of the output-voltage-versus-temperature curve from the best-fit straight line over the device’s rated temperature
range.
Note 10: Quiescent current is defined in the circuit of
Figure 1
.
Note 11: 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 (Note 2).
Note 12: Human body model, 100 pF discharged through a 1.5 kΩ resistor.
Note 13: 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.
