Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2: Guaranteed by Total Output Voltage Error Test.
Note 3: Total OUT Voltage Error is the sum of gain and offset voltage errors.
Note 4: +6.25mV = 1/16 of +100mV full-scale voltage.
Note 5: VSENSE such that output stage is in saturation.
Note 6: VOS is extrapolated from the Gain Accuracy tests.
Note 7: The device does not experience phase reversal when overdriven.
