ELECTRICAL CHARACTERISTICS (continued)
(VRS+ = 0 to 28V, VSENSE = (VRS+ - VRS- ) = 0V, VCC = +3.0V to +28V, RL = ∞, TA = TMIN to TMAX, unless otherwise noted. Typical
values are at TA = 25°C.) (Note 1)

Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2: Total OUT Voltage Error is the sum of gain and offset errors.
Note 3: 6.25mV = 1/16 of 100mV full-scale sense voltage.
Note 4: VSENSE such that VOUT is in saturation.
