NOTES: (1) Junction temperature = ambient for +25

°C tested specifications. (2) Junction temperature = ambient at low temperature limit, junction temperature = ambient

+2

°C at high temperature limit for over temperature tested 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 CMR at

± CMIR limits.
