Note 1: Limits are guaranteed by 100% testing, sampling, or correlation with worst-case test conditions.

Note 2: Includes all bias currents to other circuits connected to the V_FBpin.

Note 3: Gain = K x 5.375V; K = (I_SENSE– I_OFFSET) x [I_AC(VEAO – 0.625)]^-1; VEAO_MAX= 6V

Note 4: Guaranteed by design, not 100% production test.
