NOTES: (1) Junction temperature = ambient for +25
°C tested specifications.
(2) Junction temperature = ambient at low temperature limit: junction temperature = ambient +23
°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.
ELECTRICAL CHARACTERISTICS: VS = +5V
Boldface limits are tested at +25
°C.
RF = 402Ω, RL = 100Ω to VS / 2, and G = +2, (see Figure 3 for AC performance only), unless otherwise noted.
