(1) All voltages are measured with respect to the GND pin unless otherwise specified.
(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 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 for parameters where no limit is given, however, the typical value is a good indication of device
performance.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(4) The maximum power dissipation must be derated at elevated temperatures and is dictated by T_JMAX, θ_JC, and the ambient temperature,
T_A. The maximum allowable power dissipation is P_DMAX = (T_JMAX - T_A) / θ_JC or the number given in Absolute Maximum Ratings,
whichever is lower. For the LME49810, T_JMAX = 150°C and the typical θ_JC is 4°C/W.
(5) Human body model, 100pF discharged through a 1.5kΩ resistor.
(6) Machine Model, 220pF - 240pF discharged through all pins.
(7) The maximum operating junction temperature is 150°C.
