NOTES: (1) Junction temperature = ambient for +25°C min/max specifications.
(2) Junction temperature = ambient at low temperature limit: junction temperature = ambient +23°C at high temperature limit for over temperature min/max
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. V
CM
is the input common-mode voltage.
