(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 +2°C at high temperature limit for over
temperature specifications.
(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
