This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(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 specify performance limits. Electrical Characteristics state DC and AC electrical specifications
under particular test conditions that 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) 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

or the number given in Absolute Maximum Ratings,
whichever is lower. For the LM4917, see power de-rating currents for more information.
(3) Human body model, 100pF discharged through a 1.5kΩ resistor.
(4) Machine Model, 220pF-240pF discharged through all pins.

(1) If the product is in shutdown mode and V
DD
exceeds 3.6V (to a max of 4V V
DD
) then most of the excess current will flow through the
ESD protection circuits. If the source impedance limits the current to a max of 10mA, then the part will be protected. If the part is
enabled when V
DD
is above 4V circuit performance will be curtailed or the part may be permanently damaged.
