(2) Junction temperature = ambient at low temperature limit, junction temperature = ambient +1 °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. ELECTRICAL CHARACTERISTICS: VS = +5V Boldface limits are tested at +25 °C. RF = 1.0kΩ, RL = 100Ω, and G = +2, unless otherwise noted.
