Note 1: All voltages are measured with respect to the ground pin, unless otherwise specified.  
Note 2: 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. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which  
guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit  
is given, however, the typical value is a good indication of device performance.  
Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by T  
, θ , and the ambient temperature T . The maximum  
A
JMAX JA  
allowable power dissipation is P  
= (T  
–T )/θ or the number given in Absolute Maximum Ratings, whichever is lower. For the LM4990, see power derating  
DMAX  
JMAX A JA  
curves for additional information.  
Note 4: Human body model, 100pF discharged through a 1.5kΩ resistor.  
Note 5: Machine Model, 220pF – 240pF discharged through all pins.  
Note 6: Typicals are measured at 25˚C and represent the parametric norm.  
Note 7: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).  
Note 8: For micro SMD only, shutdown current is measured in a Normal Room Environment. Exposure to direct sunlight will increase I by a maximum of 2µA.  
SD  
Note 9: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.  
Note 10: R  
is measured from the output pin to ground. This value represents the parallel combination of the 10kΩ output resistors and the two 20kΩ resistors.  
ROUT  
Note 11: If the product is in Shutdown mode and V exceeds 6V (to a max of 8V V ), then most of the excess current will flow through the ESD protection circuits.  
DD  
DD  
If the source impedance limits the current to a max of 10mA, then the device will be protected. If the device is enabled when V is greater than 5.5V and less than  
DD  
6.5V, no damage will occur, although operation life will be reduced. Operation above 6.5V with no current limit will result in permanent damage.  
Note 12: Maximum power dissipation in the device (P  
) occurs at an output power level significantly below full output power. P  
can be calculated using  
DMAX  
DMAX  
Equation 1 shown in the Application Information section. It may also be obtained from the power dissipation graphs.
