and simulation. (C) Typical value only for information.
(2) Junction temperature = ambient for +25°C tested specifications.
(3) Junction temperature = ambient at low temperature limit; junction temperature = ambient +2°C at high temperature limit for over
temperature specifications.
(4) Current is considered positive out-of-node. V
CM
is the input common-mode voltage.
