Hello, I'm interested in using ADE9113 for measuring input voltage and input current in a traction inverter.
1) In the datasheet, it surprised me to see the input impedance of the analog pins reported as typically 3900k for the current pins, and 370k for the voltage pins. Usually, it's the other way around. Did the values perhaps get switched?
2) Is any data available about the bias current or leakage current of the analog inputs?
3) In the datasheet for ADE7912/ADE7913, TS4148 diodes are suggested for protection of the analog input pins. I understand that the reverse leakage and forward "leakage" current are important parameters when choosing a diode for this purpose. Mostly for the voltage inputs since the source impedance is typically high (about 5kOhm in my application). Has TS4148 been verified as suitable for the task? I tried to extrapolate the curves in the datasheet and it seems the typical forward current at 200mV is in the range 1-10 uA, which would cause a large error in the voltage measurement.
Best regards
