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: All voltages are measured with respect to the ground pin, unless otherwise specified.
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 LM4871, TJMAX = 150C. For
the
θJA’s for different packages, please see the Application Information section or the Absolute Maximum Ratings section.
Note 5: Human body model, 100pF discharged through a 1.5k
resistor.
Note 6: Machine Model, 220pF–240pF discharged through all pins.
Note 7: Typicals are specified at 25C and represent the parametric norm.
Note 8: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 9: The given
θ
JA is for an LM4871 packaged in an LDC08A with the Exposed–DAP soldered to an exposed 1in
2 area of 1oz printed circuit board copper.
Note 10: When driving 3
or 4 loads from a 5V supply, the LM4871LD must be mounted to a circuit board.
