SLVSAT3
– SEPTEMBER 2011
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.

(2)
Power rating at a specific ambient temperature TA should be determined with a junction temperature of 140°C. This is the point where
distortion starts to substantially increase. See power dissipation estimate in the application section of this data sheet for more
information.

Test boards conditions:
(a) 2 inches x 2 inches, 4 layers, thickness: 0.062 inch
(b) 2 oz. copper traces located on the top of the PCB
(c) 2 oz. copper ground planes on the 2 internal layers and bottom layer
(d) 4 thermal vias (10mil) located under the device package
