(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 specified for parameters where no limit is given; however, the typical value is a good indication
of device performance.
(2) All voltages are measured with respect to the ground pins, unless otherwise specified.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(4) The Differential Input Voltage Absolute Maximum Rating is based on supply voltages V
+
= 40V and V
-
= - 40V.
(5) The maximum power dissipation must be de-rated 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

-T
A
) / θ
JC
or the number given in the Absolute Maximum Ratings,
whichever is lower. For the LM4780, T
JMAX
= 150°C and the typical θ
JC
is 0.8°C/W. Refer to the THERMAL PROTECTION section for
more information.
(6) Human body model, 100pF discharged through a 1.5kΩ resistor.
(7) Machine Model: a 220pF - 240pF discharged through all pins.
(8) The maximum operating junction temperature is 150°C. However, the instantaneous Safe Operating Area temperature is 250°C.

(3) Operation is specified up to 84V; however, distortion may be introduced from SPiKe protection circuitry if proper thermal considerations
are not taken into account. Refer to the THERMAL PROTECTION section for more information.
