Note:
*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 (70ktyp)
*4: Self-excitation and oscillation type
*5: Accuracy of current monitor output is affected by the materials of the hold capacitor (C1).
The capacitor C1 must be of low dielectric absorption and have good bias and leak current characteristics.
