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.

NOTES: (1) Junction temperature = ambient for +25°C tested specifications. (2) Junction temperature = ambient at low temperature limit: junction temperature = ambient
+2°C at high temperature limit for over-temperature tested specifications. (3) Test levels: (A) 100% tested at +25°C. Over-temperature limits by characterization and
simulation. (B) Limits set by characterization and simulation. (C) Typical value only for information. (4) Current is considered positive out-of-node. VCM is the input
common-mode voltage. (5) Tested < 3dB below minimum specified CMRR at ± CMIR limits.
