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. VCM is the input common-mode voltage.

(5) Tested < 3dB below minimum specified CMRR at

± CMIR limits.
