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.
Junction temperature = ambient for 25°C specifications.
Junction temperature = ambient at low temperature limit; junction temperature = ambient + 8°C at high temperature limit for over
temperature specifications.
Current is considered positive out of node. V
CM
is the input common-mode voltage.
