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

(2) Junction temperature = ambient at low temperature limit; junction temperature = ambient +23°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 CMRR specification at ± CMIR limits.
