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.
