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. Maxim Integrated 3
