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.

NOTE
This data manual is designed using PDF document-viewing features that allow quick access
to information. For example, performing a global search on "page 0 / register 27" produces
all references to this page and register in a list. This makes it easy to traverse the list and
find all information related to a page and register. Note that the search string must be of the
indicated format. Also, this document includes document hyperlinks to allow the user to find
a document reference quickly. To come back to the original page, click the green left arrow
near the PDF page number at the bottom of the file. The hot-key for this function is alt-left
arrow on the keyboard. Another way to find information quickly is to use the PDF bookmarks.
