Note 2: Absolute Maximum Rating indicate limits beyond which damage to the device may occur.
Note 3: 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 4: Human body model, 100pF discharged through a 1.5k
resistor.
Note 5: Typical specifications are specified at +25C and represent the most likely parametric norm.
Note 6: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 7: 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
).
Note 8: All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 9: The given
θJA and θJC are for an LM4852 mounted on a demonstration board with a 4in2 area of 1oz printed circuit board copper ground plane.
Note 10: Please refer to the Output Noise vs Output Mode table in the Typical Performance Characteristics section for more details.
Note 11: Datasheet min/max specifications are guaranteed by design, test, or statistical analysis.
