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 VFB pin.
Note 3: Gain ~ K x 5.3V; K = (ISENSE – IOFFSET) x [IAC (VEAO – 0.7)]-1; VEAOMAX = 6V
Note 4: Guaranteed by design, not 100% production test.
