NOTES: (1) Junction temperature = ambient for +25°C specifications.
(2) Junction temperature = ambient at low temperature limit: Junction temperature = ambient +15°C at high temperature limit for over temperature
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.
(5) Tested < 3dB below minimum specified CMRR at ± CMIR limits.
