(1) 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 ensure specific performance limits. Electrical Characteristics state DC and AC electrical
specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the
Operating Ratings. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication
of device performance.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) The maximum power dissipation must be derated at elevated temperatures and is dictated by T_JMAX, θ_JA, and the ambient temperature
T_A. The maximum allowable power dissipation is P_DMAX = (T_JMAX–T_A)/θ_JA or the number given in Absolute Maximum Ratings, whichever
is lower. For the LM4871, T_JMAX = 150°C. For the θ_JA's for different packages, please see the Application Information section or the
absolute maximum ratings section.
(4) Human body model, 100pF discharged through a 1.5kΩ resistor.
(5) Machine Model, 220pF–240pF discharged through all pins.
(6) The given θ_JA is for an LM4871 packaged in an NGN0008A with the Exposed–DAP soldered to an exposed 1in² area of 1oz printed
circuit board copper.
