Package."
(1) All voltages are measured with respect to the ground 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 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.
(3) If Military/Aerospace specified devices are required, please contact the TI 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
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 LM4673, T
JMAX
= 150°C. The typical θ
JA
is 99.1°C/W for the DSBGA package.
(5) Human body model, 100pF discharged through a 1.5kΩ resistor.
(6) Machine Model, 220pF – 240pF discharged through all pins.
