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
I
) at any pin exceeds power supplies (V
I
<
GND or V
I
>
V
+
), the current at that pin should be limited to 5 mA.
Note 3:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin. The machine model is a 200 pF capacitor discharged
directly into each pin.
Note 4:
Reflow temperature profiles are different for lead-free and non-lead-free packages.
Note 5:
The junction to ambient thermal resistance (
θ
JA
) is specified without a heat sink in still air.
Note 6:
Typicals are at T
J
= T
A
= 25C and represent most likely parametric norm.
Note 7:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8:
Accuracy is defined as the error between the measured and reference output voltages, tabulated in the Transfer 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 9:
Changes in output due to self heating can be computed by multiplying the internal dissipation by the thermal resistance.
Note 10:
Source currents are flowing out of the LM94022. Sink currents are flowing into the LM94022.
Note 11:
Guaranteed by design.
Note 12:
The input current is leakage only and is highest at high temperature. It is typically only 0.001μA. The 1μA limit is solely based on a testing limitation and
does not reflect the actual performance of the part.
Note 13:
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 5.0.
