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 specific 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: When the input voltage (V
Note 3: The Human Body Model (HBM) is a 100 pF capacitor charged to the specified voltage then discharged through a 1.5 kΩ resistor into each pin. The
Machine Model (MM) is a 200 pF capacitor charged to the specified voltage then discharged directly into each pin. The Charged Device Model (CDM) is a specified
circuit characterizing an ESD event that occurs when a device acquires charge through some triboelectric (frictional) or electrostatic induction processes and then
abruptly touches a grounded object or surface.
Note 4: The junction to ambient temperature resistance (θ
Note 5: Typicals are at T
Note 6: Limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 7: Accuracy is defined as the error between the measured and reference output voltages, tabulated in the Conversion Table at the specified conditions of
supply gain setting, voltage, and temperature (expressed in °C). Accuracy limits include line regulation within the specified conditions. Accuracy limits do not
include load regulation; they assume no DC load.
Note 8: Changes in output due to self heating can be computed by multiplying the internal dissipation by the temperature resistance.
Note 9: Source currents are flowing out of the SM72480. Sink currents are flowing into the SM72480.
Note 10: The 1 µA limit is based on a testing limitation and does not reflect the actual performance of the part. Expect to see a doubling of the current for every
15°C increase in temperature. For example, the 1 nA typical current at 25°C would increase to 16 nA at 85°C.
Note 11: Line regulation (DC) is calculated by subtracting the output voltage at the highest supply voltage from the output voltage at the lowest supply voltage.
The typical DC line regulation specification does not include the output voltage shift discussed in Section 4.3.
Note 12: The curves shown represent typical performance under worst-case conditions. Performance improves with larger overhead (V
and lower temperatures.
Note 13: The curves shown represent typical performance under worst-case conditions. Performance improves with larger V
temperatures.
