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_FB pin.
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.
