1: Accuracy warranty range for current monitor output
2: Equivalent errors are not included in current monitor output accuracy.
3: With built-in pull-down resistance (70kΩ typ)
4: Self-excitation and oscillation type
5: Accuracy of current monitor output is affected by the materials of the hold capacitor (C1).
