SLVS686 – OCTOBER 2006

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.
