(1)
Junction temperature = ambient for +25°C specifications.
(2)
Junction temperature = ambient at low temperature limits; junction temperature = ambient +7°C at high temperature limit for over temperature.
(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.
