NOTE: (1) Fot the most current specifications and package information, refer to our web site at www.ti.com. (2) Models with a slash (/) are available only in Tape
and Reel in the quantities indicated (e.g., /1K indicates 1000 devices per reel). Ordering 1000 pieces of ADS823E/1K” will get a single 1000-piece Tape and Reel.
PACKAGE/ORDERING INFORMATION
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments 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: (1) Stresses beyond those listed under "absolute maximum ratings" may cause
permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated under
"recommended operating conditions" is not implied. Exposure to absolute-maximum-
rated conditions of extended periods may affect device reliability.
