(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. VCM is the input common-mode voltage.
