Electrical Characteristics
Components
The following specifications apply for V
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2: 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 3: Human body model, 100pF discharged through a 1.5kΩ resistor.
Note 4: Typical specifications are specified at +25˚C and represent the most likely parametric norm.
Note 5: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level). Datasheet min/max specification limits are guaranteed by design, test,
or statistical analysis.
Note 6: : Machine Model ESD test is covered by specification EIAJ IC-121-1981. A 200pF cap is charged to the specified voltage, then discharged directly into the
IC with no external series resistor (resistance of discharge path must be under 50 Ohms).
Note 7: The LDA10A package has its Exposed−DAP soldered to an exposed 2in
Note 8: All voltages are measured with respect to the ground pin, unless otherwise specified.
