(1) Junction temperature = ambient for +25°C specifications.

(2) Junction temperature = ambient at low temperature limits; junction temperature = ambient +9°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. VCM is the input common-mode voltage.

(5) Tested < 3dB below minimum specified CMRR at ±CMIR limits.
