(4) I_BI is referred to a differential output offset voltage by the following relationship: V_OD(offset) = I_BI*2R_F
(5) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
(6) Short circuit current should be limited in duration to no more than 10 seconds. See POWER DISSIPATION of Application Information for
more details.
