(1) Test levels: (A) 100% tested at +25°C. Over temperature limits set by characterization and simulation. (B) Limits set by characterization
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 +18°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.
