Junction temperature = ambient for +25
°
C specifications.
Junction temperature = ambient at low temperature limits; junction temperature = ambient +15
°
C at high temperature limit for over temperature specifications.
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.
Current is considered positive out-of-node. V
is the input common-mode voltage.
Tested < 3dB below minimum specified CMRR at
±
CMIR limits.
