Note 2: All voltages are measured with respect to the GND pin unless other wise specified.

Note 3: 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 that

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 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX,

currents for more information.

Note 5: Human body model, 100 pF discharged through a 1.5 k

Ω resistor.

Note 10: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).

Note 11: Datasheet minimum and maximum specification limits are guaranteed by design, test, or statistical analysis.

Note 12: Output power is measured at the amplifier’s package pins.
