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, θJA, and the ambient temperature, TA. The maximum
allowable power dissipation is PDMAX =(TJMAX -TA)/θJA or the number given in Absolute Maximum Ratings, whichever is lower. For the LM4854, see power derating
currents for more information.
Note 5: Human body model, 100pF discharged through a 1.5k
resistor.
Note 6: Machine Model, 220pF-240pF discharged through all pins.
Note 7: The given
θJA is for an LM4854 packaged in an LDA14A with the Exposed-DAP soldered to an exposed 2in2 area of 1oz printed circuit board copper.
Note 8: Typicals are measured at 25C and represent the parametric norm.
Note 9: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 10: Datasheet minimum and maximum specification limits are guaranteed by design, test, or statistical analysis.
Note 11: Output power is measured at the amplifier’s package pins.
Note 12: When driving 4
loads and operating on a 5V supply, the LM4854LD must be mounted to a circuit board that has a minimum of 2.5in2 of exposed,
uninterrupted copper area connected to the LLP package’s exposed DAP.
