(6) Positive current corresponds to current flowing into the device.
(7) Drift determined by dividing the change in parameter distribution at temperature extremes by the total temperature change.
(8) Input bias current drift with temperature can be either positive or negative for a given sample.
(9) +PSRR definition: [|ΔV_OUT/ΔV⁺| / A_V], −PSRR definition: [|ΔV_OUT/ΔV^−| / A_V] with 0.1V input voltage. ΔV_OUT is the change in output
voltage with offset shift subtracted out.
